The Plane That Accidentally Ended Up in Space

0:01 April 15th, 1986. US Air Force Major Brian Shaw streaks through the stratosphere 15 miles over Colonel Gaddafi's Libya in his LED SR-71 Blackbird. Flying too high for enemy fighters to reach, too fast for missiles to catch, virtually invisible to radar. Not a single one has been shot down in over two decades of operation. But a series of course corrections has temporarily slowed Shaw's Blackbird's speed. Suddenly, he sees red warning lights flaring across his instrument panel. Somehow, dated Soviet built Libyan service to air batteries have locked on to the world's fastest aircraft. The SR71's only hope was to hit the gas. Everyone was about to find out if the Blackbird could actually outrun a

0:48 missile. The challenge. The development of the SR71 can be directly linked to an infamous incident involving its predecessor, the Loheed U2 spy plane. On May 1st, 1960, a U2 flown by Francis Gary Powers was disabled over Soviet airspace. Hit by surfaceto-air missiles, the aircraft plummeted from 70,000 ft to 30,000 ft before Powers could bail out of the damaged cockpit. Powers survived but was immediately captured by Soviet forces. President Eisenhower's cover story about a weather research aircraft quickly fell apart when the Soviets proudly displayed the down plane surveillance equipment at a press conference. The U2 incident became an immediate diplomatic catastrophe, straining already tense cold war

1:34 relations. Worst of all for Washington was the realization that if the Soviets had shot down one spy plane, they could do it again. The only way to avoid a repeat of this embarrassing situation would be to create a new aircraft that could fly so high and so fast that no existing air defense system could touch it. The aircraft would have a radar profile so small that it would be nearly undetectable to the enemy. Fortunately, Lockheed was already on the case. The company's vice president and head of its skunk works advanced development team. The legendary Clarence Kelly Johnson had been the chief designer of the U2. Even before the May 1960 incident, he had anticipated that the aircraft's days would be numbered as Soviet air defenses improved. With his uncompromising standards and innovative thinking,

2:19 Johnson had begun developing concepts for an aircraft that would be virtually undetectable by any radar and untouchable by any missile. Now under pressure from Washington to offer a solution as quickly as possible, Johnson promised his team would succeed in its toughest assignment yet, to create a new spy plane with a minimal radar cross-section that could fly above 80,000 ft at speeds exceeding Mach 3 and to have it flying in a mere 20 months. A timeline that most aerospace experts considered impossible. The project began under the CIA's tight control as a successor to the U2. Initially designated the A12, the Skunk Works operated under extraordinary secrecy with the project site at Burbank concealed behind tall barriers and security tighter than at most nuclear facilities. Johnson's team

3:06 worked at breakneck speed and by April 1962, just as he had promised, the first A12 prototype was ready. Inventing the future. The A12 prototype that emerged from Skunkworks in 1962 was unlike any aircraft ever built. It was not so much a continuation of the U2 as an entirely new creation. Johnson would later recall, quote, "Everything had to be invented." Everything. Johnson and his team's design choices reflected their necessity for both unprecedented aerodynamic performance and a vastly reduced radar profile. This would begin with the A12's sleek dart-like shape, a radical departure from conventional aircraft of the era. In order to reflect radar

3:53 energy away from its source, the prototype's vertical stabilizers were caned inward. The fuselage sides were flattened with tapering edges, while sawtooth-shaped sections incorporated special radar absorbing materials, an early attempt at what would later be called stealth technology. The A12 featured tapered chines, sharp edges that ran along either side of the fuselage from the nose to the wing roots. These chines represented a breakthrough in integrated design, serving three crucial functions simultaneously. They generated vortices that improved stability at high speeds. They provided additional lift to the airframe and they scattered incoming radar signals away from their source. However, the extreme speeds at which the A12 was expected to travel presented another fundamental challenge. Heat.

4:39 With temperatures on the aircraft's leading edges expected to exceed 1,000° F during flight of Mach 3 and beyond, conventional aluminum airframes would simply melt. This challenge forced Johnson's team to use titanium alloy for 85% of the structure, a material that provided the strength of stainless steel at a fraction of the weight while withstanding the intense heat of supersonic flight. Titanium proved exceptionally difficult to work with. The brittle alloy would shatter if mishandled, causing immense frustration on the assembly line. Conventional cadmium plated steel tools fractured the titanium on contact, forcing skunkworks to design and fabricate new tools themselves made of titanium. Adding to these complications, metallurgical contamination was a persistent problem. At one point, 80% of

5:26 the delivered titanium was rejected on these grounds. To handle the massive temperature variations, the A12 skin panels were manufactured to fit loosely on the ground, only achieving proper alignment as the airframe heated up during flight. Nevertheless, this design feature, along with the lack of a proper fuel sealing system, meant the aircraft leaked fuel while stationary, a characteristic that would become legendary among ground crews. Meanwhile, the canopy of the single seat cockpit was equipped with special quartz glass to withstand extreme temperatures with the outer windscreen made of three layers and cooling sections between them. For propulsion, the A12 was designed around the revolutionary Prattton Whitney J58 engine. Though initial flight testing began with the

6:12 less powerful J75 due to J58 development delays, each engine could produce 25,000 lb of thrust with afterburners engaged, allowing the aircraft to reach speeds over 2,000 mph. The engines functioned as traditional jet engines during takeoff and transition to supersonic speeds before essentially becoming specialized ramjets at high Mach numbers. These engines would require equally sophisticated inlet systems to efficiently process the enormous volumes of air needed at Mach 3. The prototype featured a complex system of movable cones and bypass doors that would automatically adjust to maintain optimal air flow at various speeds. Due to the extreme operating conditions, the engines would also need specialized fuel. Conventional jet fuel would have been far too volatile at the

6:59 temperatures the A12 experienced during flight. Engineers developed JP7, a unique high flashoint fuel specifically designed for the aircraft. Pilot Colonel Rich Graham later explained its unusual properties, saying, quote, "I've already seen a crew chief throw a match, a cigarette butt, into this JP7, and it just extinguishes." This high flash point created another challenge. Standard ignition systems couldn't light the fuel. The solution was triethylorine or TEB, a chemical so volatile it ignites spontaneously when exposed to air. Graham described it vividly. Quote, "Each engine has a 1 and a/4 pint. If I had it in a squirt gun and I squirted it into the atmosphere, it goes kaboom. It explodes with contact with the

7:46 atmosphere." Each engine carried just enough TEB for 16 starts. There's a precisely metered amount injected to initiate combustion each time the engines needed to be started or the afterburners engaged. Pilots could actually see when TEB was ejected as it produced a distinctive green flash visible in the exhaust. To the test, the A12 prototype was ready, but the US government was keen to keep the project secret for as long as possible. Therefore, trials would take place at the same remote testing location deep in the Nevada desert where the U2 had been tested. Officially called Groom Lake, this highly classified facility would soon become the stuff of legend as the semi- mythical Area 51. Its existence

8:32 not publicly acknowledged by the CIA until 2013. It was here where on April 30th, piloted by lucky test pilot Lewis Schul, the A12 prototype took to the skies for the first time. still in its natural titanium finish rather than the black paint that would later become iconic. This first flight was kept brief and below the aircraft's potential, Schul kept the landing gear down throughout the flight as a precaution, reaching just 340 mph and 30,000 ft during this initial 35-minute test. While modest compared to what would come, this first flight was crucial in validating the basic handling characteristics of a design unlike anything that had flown before. Over the following months, as testing progressed, the A12 gradually pushed

9:19 toward its design capabilities. On July 20th, 1963, the A12 achieved a sustained speed above Mach 3 at an astounding altitude of 78,000 ft, breaking records nearly every time it flew. The aircraft's outstanding radar deflection capabilities were also confirmed during testing, with radar cross-section measurements showing an incredible 90% reduction compared to conventional aircraft of similar size. These tests revealed practical challenges as well. At such extreme speeds, traditional navigation methods became obsolete. Visual references that pilots had relied on for decades, highways, rivers, and metropolitan areas were rendered meaningless, replaced by mountain ranges, coastlines, and large bodies of water as the only features

10:04 that could be distinguished at Mach 3. After completing its testing phase at Groom Lake, the A12 moved from experimental aircraft to operational spy plane. In 1965, with the Vietnam War escalating, the CIA began deploying A12s to Kadina Air Base on Okinawa, Japan under an operation cenamed Black Shield. The aircraft would conduct missions over North Vietnam, North Korea, and other critical areas in Asia, providing the United States with vital intelligence that satellites of the era simply couldn't match. A12 operational missions were conducted in absolute secrecy. The aircraft flew so high and so fast that even when detected on radar, they would be gone before fighter aircraft could be scrambled or surfaceto-air missiles

10:49 could reach their altitude. The pilots rather than being military officers were civilian CIA employees operating under non-official cover. If captured, they would have no military protection under international [Music] conventions. From A12 to SR71. However, while the A12 carried out its CIA operations, the US Air Force was busy developing its own version of the aircraft. The Air Force had first ordered its own variant, initially designated the R12 by Lockheed as early as December 1962. Their version would be longer and heavier than the original A12, primarily to accommodate more fuel and a twoerson crew. Unlike the singles seat A12, the

11:35 Air Force wanted their aircraft to have tandem cockpits, one for the pilot and the second for a reconnaissance systems officer or RSO, who would navigate and operate the sophisticated surveillance systems. The RSO's expertise would be crucial for managing the complex electronic and photographic equipment during marathon reconnaissance missions. The Air Force variant also featured reshaped fuselage chines and redesigned engine cells. While the A12 had been primarily designed to carry a high resolution camera, the new aircraft would carry a more diverse payload including signals intelligence sensors, sidelooking airborne radar, and multiple photographic systems. By 1964, with Cold War tensions high and a presidential election approaching, politics entered the picture. Republican presidential nominee

12:22 Barry Goldwater had been criticizing President Lyndon B. Johnson's administration for falling behind the Soviet Union in developing new weapons. Seeking to counter this criticism, Johnson made a surprising decision to reveal the existence of the top secret aircraft program. In July 1964, in what would become a famous announcement, President Johnson publicly disclosed the existence of this new reconnaissance aircraft, referring to it as the RS71. However, Air Force Chief of Staff General Curtis Lane had lobbied for the SR designation for strategic reconnaissance instead of RS for reconnaissance strike. Either before or after the speech, sources differ. The designation was changed to SR71, though the president's actual words remained RS71 in his

13:11 delivery. That same year, the aircraft received its distinctive black paint, a practical decision rather than an aesthetic one. Engineers had realized that black paint both absorbs and emits heat efficiently, helping to dissipate the extreme temperatures generated during high-speed flight across the entire airframe. This functional black finish gave rise to the name that would captivate the public imagination. Blackbird. The Blackbird takes flight. On December 22nd, 1964, the first SR71 performed its maiden flight from Air Force Plant 42 in Palmdale, California with lucky test pilot Bob Gilland at the controls. Just over a year later, in January 1966, the first

13:58 SR-71s entered service with the 4200 Strategic Reconnaissance Wing at Be Air Force Base in California. This unit would later be redesated as the ninth strategic reconnaissance wing. While the CIA's A12 had operated in complete secrecy, the SR71 would fly over missions with USAF markings. A12 pilots had operated as civilian CIA employees, but SR-71 pilots were uniformed Air Force officers who carried Geneva Convention's ID cards in case they were shot down. On March 21st, 1968, Majors Jerome Ali and Edward Payne flew the first operational SR71 sorty from Kadina Air Base in Okinawa, gathering intelligence over North Vietnam. As the A12 program

14:45 wound down that same year, the SR-71 took over the vital reconnaissance role in Southeast Asia, quickly proving its value by providing detailed intelligence about strategic hotspots throughout the region. The local personnel at Kadina nicknamed the sinister looking SR-71 Habu after a venomous pit viper native to the region. The name stuck, becoming one of several affectionate nicknames for the blackbird among those who worked with it. Flying at over 80,000 ft, more than 15 miles above the Earth, the SR71 could survey 100,000 square miles of territory in a single hour. Its sophisticated camera systems could resolve objects as small as 6 in from its cruising altitude, while its side looking airborne radar could penetrate cloud cover to map terrain and

15:32 track vehicle movements. Yet, this extraordinary reconnaissance capability would have been worthless if the aircraft couldn't survive to bring its intelligence home. When surfaceto-air missile launches were detected, the standard Blackbird evasive action was remarkably straightforward. Simply accelerate and outpace the threat. This strategy proved remarkably effective. Over 4,000 missiles were fired at SR-71s during their operational career, yet none ever managed to score a hit. The few losses the program did experience came from mechanical failures rather than enemy action. Flying the Blackbird was an experience unlike any other in aviation. In preparation for each mission, pilots and RSOs followed a specific dietary protocol that included a high protein,

16:20 lowresidue meal of steak and eggs. After their meal, crews would undergo a quick medical examination before dawning their specialized pressure suits, effectively the same type used by astronauts. These suits were essential. At operating altitudes, blood would boil without pressurization, and if ejection became necessary at Mach 3, pilots would face temperatures up to 450° F from air friction alone. For those fortunate enough to fly it, the SR71 offered an experience that transcended ordinary aviation. Air Force Colonel Jim Watkins expressed the almost transcendent quality of Blackbird missions. Quote, "At 85,000 ft in Mach 3, it was almost a religious experience. Nothing had prepared me to fly that fast. My god, even now I get goosebumps

17:07 remembering it. The view from the cockpit was equally extraordinary. Flying at the edge of space, pilots could see the curvature of the Earth while looking up into a sky that appeared almost black. Below them, the world passed by at a rate of nearly a mile every second, rendering conventional navigation references useless. The aircraft offered a perspective of our planet that until that time had been available only to a handful of astronauts. Yet, while the cockpit came with an incredible view, it was also a somewhat extreme environment. During Mach 3 flight, the exterior of the windscreen could reach temperatures of 600° F, while the interior maintained a more modest 250° F. Still hot enough, the crews found innovative uses for it.

17:53 Colonel Graham recalled, quote, "If I took that tube food and jammed it against my window in the front windscreen, which at the outside is 622° F at Mach 3.2, and if I gave it about a minute and a half on both sides, and squeeze the tube to normalize the temperature, it went down a lot better warm than it did cold. You improvise up there, and that was my in-flight oven." Missions typically lasted between 3 and 4 hours, though some stretched to eight or more. The SR-71's most notable missions came during the 1973 Yam Kapoor war when it flew from the east coast of the United States to the Middle East and back, providing crucial intelligence directly to President Nixon. Graham explained, quote, "The president wanted to find out whether the Arabs and the

18:38 Israelis had really moved back from the front line like they said they did." He went over there, took the imagery, came back, and showed photographic proof they were both lying about where their forces were. He called both countries and said, "Get them back. I've got proof you're not where you're supposed to be." That's what ended the Yamapour war. During operations in Northern Europe, on rare occasions, with exceptional visibility, Blackbird crews could spot Soviet interceptors trailing far below them, sometimes up to 200 m away, futilely attempting to intercept the much faster reconnaissance aircraft. Despite the best efforts of Soviet pilots flying the Mig25 Foxbat, the fastest interceptor in their arsenal, the SR71 always remained untouchable, slipping away at speeds no other

19:24 aircraft could match. The SR71's operational tempo was limited by its intensive maintenance requirements. On average, each aircraft could fly only once per week due to the lengthy preparations needed. Very often, an SR-71 would return with rivets missing, delaminated panels, or damaged inlets requiring repair or replacement. In some cases, the aircraft wouldn't be ready to fly again for a month. Despite these challenges, the intelligence gathered by the Blackbird proved worth every hour of maintenance and every drop of the specialized JP7 fuel that leaked from its tanks. The SR71 provided American leaders with crucial information that simply couldn't be obtained any other way, helping to navigate the Cold War's dangerous waters

20:11 while remaining above the prey. becoming legend. The SR71's extraordinary capabilities were officially recognized on September 1st, 1974 when it claimed the record for speed over a recognized course by flying from New York to London in just 1 hour 54 minutes 56.4 seconds. This flight piloted by USAF Major James Sullivan with Null Whitfield as reconnaissance systems officer maintained an average speed of approximately Mach 2.72, including slowing down for midair refueling. For comparison, the fastest commercial Concord flight between those cities took nearly 3 hours, while a typical airliner flight lasted more than 6 hours. The Blackbird continued to break

20:58 records throughout the 1970s. On July 28th, 1976, two more world records were set that remain unbeaten to this day. Piloted by Captain Robert Helt, SR71 serial number 617962 reached an absolute altitude record for sustained horizontal flight of 85,69 ft. That same day, another SR71 set an absolute speed record of 2,193.2 mph, equivalent to around Mach 3.3. Nevertheless, perhaps the Blackbird's finest hour would come on April 15th, 1986. Following American air strikes on Tripoli in response to Libyan support for terrorism, Major Brian Shaw and his RSO Walter Watson were tasked with

21:44 post-strike reconnaissance. As they raced their SR71 across the hostile territory, Libyan air defenses activated. Multiple surfaceto-air missile sites began tracking the Blackbird. Warning lights illuminated in the cockpit as radar lock-ons were detected. Faced with missiles climbing toward their aircraft, Schul pushed the throttles forward beyond their usual operational settings. The Blackbird responded immediately, accelerating well beyond its official maximum speed. Schul would later recall, quote, "The plane was flying faster than any of us had ever seen. We weren't really sure exactly how fast we were going because the instruments only displayed up to Mach 3.5. The missiles fell away behind them as the Blackbird escaped the threat through

22:29 sheer velocity, proving once again that the SR71's primary defense was simply to accelerate beyond the reach of whatever was trying to catch it. Shell and Watson returned safely with their valuable intelligence, having demonstrated in the most dramatic fashion possible why no Blackbird was ever lost to enemy fire. This incredible feat to outperform even its official specifications when pushed to its limits. The following year, on June 29th, 1987, another SR71 mission would demonstrate both the aircraft's vulnerability and its international significance. During a routine Baltic Express mission, a carefully planned flight path through the narrow corridor of international airspace between Sweden and the Soviet block, an SR71 suffered a

23:15 serious engine explosion while cruising at around 65,000 ft. The crippled aircraft violated Swedish airspace as the pilots struggled to maintain control. Unarmed Swedish SAB 37 Vegan fighters were scrambled to investigate and recognizing the Blackbird was in distress, escorted it safely toward Danish airspace. What remained classified for over 30 years was that multiple Soviet MiG25s had been launched with orders to shoot down the damaged SR71. NSA data later revealed that a MIG25 had actually locked a missile onto the struggling Blackbird, but the presence of the Swedish escort fighters may have prevented the Soviets from firing. In 2018, the four Swedish pilots involved were awarded medals from the USAF for their actions, a remarkable

24:02 footnote to Cold War history that remained secret for decades. Last. Despite its unmatched capabilities, the SR71 program faced increasing scrutiny as the 1980s progressed. The aircraft was expensive to operate with estimates ranging from $85,000 to $200,000 per flight hour. Maintenance demands remained high, and the Specialized JP7 Fuel required its own dedicated tanker aircraft, the KC135Q, for mid-air refueling. Critics argued the satellite reconnaissance was making the Blackbird obsolete. Supporters countered the satellites followed predictable orbits, allowing adversaries to hide assets during overflights, while the SR71 could

24:48 arrive unpredictably and deliver imagery within hours instead of days. The debate ended in 1989 when, largely for political and budgetary reasons rather than operational ones, the Air Force retired the SR71 fleet. However, before consigning the Blackbird to history, the Air Force decided to have it make one final record-breaking journey. On March 6th, 1990, Lieutenant Colonel Ed Yielding and Lieutenant Colonel Joseph JT Vita took to the skies in SR71 serial number 617972 for what would be the aircraft's final operational flight in Air Force service. Their mission to fly coast to coast across the United States from Los Angeles to Washington DC and then

25:34 deliver the aircraft to its final home at the Smithsonian Institution's National Air and Space Museum. What followed was an astonishing display of the Blackbird's capabilities. The SR71 traversed the 2,44 mile journey between the east and west coasts in just 67 minutes 54 seconds, achieving an average speed of 2,124 mph over Mach 2.7. During the flight, the crew set four new speed records. Los Angeles to Washington DC in 64 minutes 20 seconds, West Coast to East Coast in 67 minutes 54 seconds, Kansas City to Washington DC in just under 26 minutes, and St. Louis to Cincinnati in 8 minutes 32 seconds. The National Aeronautic Association accepted all four records,

26:21 while Air and Space Magazine reported that the aircraft had reached a top speed of 2,242 mph over Mach 2.9 at one point during its journey. After landing, this remarkable aircraft that had served its country for decades taxied to a stop before a waiting crowd of dignitaries and aviation enthusiasts. The significance of the moment wasn't lost on elected officials. 2 days after the flight, Senator John Glenn, the first American to orbit the Earth, addressed the United States Senate with a pointed rebuke of the decision to retire the aircraft. Quote, "Mr. President, the termination of the SR71 was a grave mistake and could place our nation at a serious disadvantage in the event of a future crisis. Yesterday's historic transcontinental flight was a sad

27:07 memorial to our short-sighted policy in strategic aerial reconnaissance. Recognizing this capability gap, Congress voted in 1994 to allocate $und00 million to reactivate three SR71s. The aircraft returned to limited service in 1995, flying operational missions until 1998 when final retirement came. Even then, the Blackbird wasn't completely grounded. NASA continued to operate two airframes until 1999, using them as high-speed, high altitude research platforms. Glenn's words would prove pressure. The decision proved controversial among military leaders, particularly when just months later, during Operation Desert Storm, General Norman Schwarzoff requested SR-71

27:52 reconnaissance that was no longer available. On October 9th, 1999, at an air show at Edwards Air Force Base, the SR71 made its final flight. Piloted by NASA crew members Roger Smith and Robert Meyer, the aircraft reached Mach 3.21, equivalent to 2,463 mph and an altitude of 80,100 ft, more than twice the height at which commercial airliners typically cruise. After reaching these impressive figures, the Blackbird returned for three flybys at the crowd. The elegance of its design moved some onlookers to tears as they witnessed the end of an era. The following day was to have featured the true final flight with a crew including Marta Bone Meyer who had

28:38 made history as the first female SR-71 crew member. However, a fuel leak prevented this flight, making October 9th the Blackbird's final journey into the stratosphere. In its 34-year career, from first flight to retirement, the SR71 has set speed and altitude records that remain unbroken, gathered intelligence that shaped Cold War decision-making, and captured the imagination of aviation enthusiasts worldwide. Even after its retirement, no aircraft has managed to combine the Blackbird's speed, altitude, range, and sensor capabilities, making it quite literally the high point of man reconnaissance aviation.
