The Cold War had established an uneasy atmosphere in the air over the borders, when American planes and Soviet planes were often able to see each other and were sometimes just an inch separated by navigational error. The United States and the Soviet Union were never directly involved in a conventional war against one another, but their air forces had numerous encounters in reconnaissance, surveillance, training and transport activities. These encounters may quickly get out of hand, and an otherwise routine flight can become a deadly encounter in seconds.

American crews were often given missions to fly over heavily-defended Soviet territory. Some aircraft were engaged in deliberate electronic intelligence, radar surveillance, or photographic missions of military installations, or were on routine flights that strayed into sensitive areas. The threat was especially great because unauthorized planes were regarded by Soviet air defense as potential threats in their vicinity. A wrong position, radio failure or a border dispute over the airspace could, for example, prove deadly.

The following incidents illustrate how a tense aerial stand-off of the Cold War could turn deadly fast. These range from patrol bombers to spy planes, transports to reconnaissance planes. Others, both crews, were able to survive because of emergency landings or ejection, and others did not come home. These meetings present a picture of the hazards facing American airmen flying in the Soviet sphere during one of the most perilous eras in the history of air travel.

1. PB4Y-2 Privateer

The PB4Y-2 Privateer is a long-range U.S. Navy patrol bomber based on the B-24 Liberator. It was useful in reconnaissance and maritime surveillance due to its size, range and special equipment. This type of aircraft was also used during the Cold War for dangerous flights to gather information on enemy communications and radar activities. The operations frequently kept crews in proximity to areas where the Soviets were on constant alert to their air defenses.

A 1950 shootdown of the Baltic:

• Soviet fighters intercepted the aircraft
• Privateer was attacked over Baltic Sea
• Ten crew members were killed
• Incident occurred on April 8, 1950
• Early deadly Cold War confrontation

Privateer called “Turbulent Turtle” met the Soviet La-11 fighters over the Baltic Sea on 8th April 1950. The aircraft was intercepted and shot down, all ten crew members of the plane were killed. The event became one of the first deadly clashes of American and Soviet troops in the early days of the Cold War. The situation highlighted the dangers involved in reconnaissance missions as they were flown over the sensitive Soviet controlled territory.

Important, of course, was the loss of the Privateer, especially since both superpowers were actively and speedily developing their intelligence programs. American personnel tried to find out more about the Soviet military force, and Soviet forces tried to defend the airspace from such flights. It was a foretaste of the dangers that would be encountered in the future as aerial surveillance became more critical to Cold War strategy.

2. T-39 Sabreliner

The T-39 Sabreliner was a training and utility aircraft for the U.S. Air Force that was not armed. The Sabreliner wasn’t designed to fight its way out of an interception like heavily armed combat aircraft. One left Wiesbaden Air Base on a routine training flight January 28, 1964. It was reported that he entered East Germany airspace due to navigational error or bad weather, and landed in very sensitive territory of the divided continent.

Fatal East German Interception:

• Aircraft reportedly entered East German airspace
• Soviet radar detected the aircraft
• Communication attempts apparently failed
• Two MiG-19 fighters intercepted it
• Three American airmen were killed

The plane was spotted by Soviet radar operators at an average speed of about 500 mph. An effort was made to contact the crew, but there apparently was no communication, perhaps due to a radio failure. The Soviet commanders then scrambled two MiG-19 fighters to intercept the aircraft near Erfurt. The Sabreliner was unarmed and its mission profile was non-threatening, but the Soviet fighters still managed to shoot and kill the Sabreliner in mid-air.

The three American airmen on the Sabreliner were all killed. The incident demonstrated that an ordinary air flight could be lethal if an American plane penetrated Soviet bloc airspace. The aircraft did not have to do an aggressive mission, or to carry weapons, to get a military response. In the Cold War days, if someone showed up where the Soviet commanders thought that an aircraft shouldn’t be, they could initiate an armed interception.

3. RB-47H

The RB-47H was developed for one of the cold war’s most sensitive missions electronic intelligence collection. It was used to collect data on Soviet radar and communications systems and was based on the B-47 Stratojet. The missions were vital to the American intelligence picture because it was important to understand how the Soviet military detected, tracked and responded to approaching aircraft in order to see how its air defense network functioned.

The Barents Sea Encounter:

• Intelligence mission over Barents Sea.
• Soviet MiG-19 intercepted RB-47H
• Armed defense was said to have been turned off.
• Four American sailors died in the crash.
• Two survivors were picked up

This RB-47H was flying over the Barents Sea on an intelligence-gathering mission on July 1, 1960, when it was intercepted by a Soviet MiG-19. The American plane was performing in international airspace and the encounter was soon a violent one. During the confrontation, the Soviet fighter knocked out the defense, leaving the reconnaissance plane helpless, according to the source material.

The four Americans on the ship died in the attack. Two of the others survived and were arrested by the Soviets, who kept them prisoner for over a year until 1961. The outcome was to demonstrate in the most spectacular fashion the hazards of electronic reconnaissance. The aircraft’s mission was to gather information, not to attack targets, but the aircraft was in the path of Soviet interceptors, being operated close to Soviet territory.

4. RU-8 Seminole

The RU-8 Seminole was an aircraft modified for the U.S. Army for electronic surveillance and reconnaissance. It wasn’t very large, but its subtle demeanor hid its delicate operations. American airplanes overflew the border areas and could thus observe what was going on and gather information, but it was also important for them to use caution in flying close to some of the most heavily patrolled airspace in the world.

A Dangerous Navigation Error:

• Intelligence mission near Turkish-Soviet border
• Aircraft encountered navigation problems
• It entered Soviet-controlled airspace
• Soviet fighters moved to intercept
• All four crew members survived

During a reconnaissance flight over the Turkish-Soviet border on 21 October 1970, an RU-8 had to deal with navigation issues. The aircraft entered into the airspace of the Soviet Union over the Armenian Soviet Socialist Republic. The Soviet forces acted swiftly, launching fighters to intercept the aircraft once they had been detected. The incident could have well have resulted in another American aircraft and crew being lost.

Instead, the pilot was able to make a forced landing. The crew of four were all able to survive and were rescued. The aircraft’s intrusion resulted in a serious military response, but the crew’s survival ruled out the episode from becoming an even bigger diplomatic crisis. It also showed the potential speed at which an error in navigation can escalate a reconnaissance flight to an international confrontation in the Cold War era.

5. RB-66 Destroyer

The RB-66 Destroyer evolved from the B-66 bomber and was modified for reconnaissance, electronic intelligence and radar jamming operations. It was fitted with equipment to observe and learn more about enemy air defense networks and radar installations. Such aircraft were often deployed at European air bases for missions near the front lines of the Soviet bloc with the aim of collecting valuable information.

The East German Shootdown:

• Training and reconnaissance flight
• Aircraft crossed into East German territory
• Soviet MiG-19 fighters intercepted it
• RB-66 was destroyed during attack
• Three crew members successfully survived

On March 10, 1964, an RB-66 from Toul-Rosières Air Base in France was on a training and reconnaissance mission over enemy territory. The plane had strayed into East Germany by mistake. When the invaders were discovered, the Soviet MiG-19 fighters responded by flying to intercept the U.S. planes and firing on them over the East German border.

The RB-66 was destroyed but the three men who had been on board, managed to eject from the aircraft and escape. The airmen were caught by the East Germans, creating a diplomatic and military situation. The crew was finally released after some two months of negotiations. Many similar incidents resulted in people being killed, but their survival was a rare positive outcome at a time when it was common.

6. U-2

The U-2 was one of the most famous symbols of the Cold War aerial reconnaissance. The high altitude aircraft was designed by aircraft engineer Kelly Johnson and could fly above 70,000 feet and was specially developed for intelligence gathering in hard-to-reach regions. It had an outstanding altitude and it was thought that this would make it difficult for the enemy to intercept.

The 1960 U-2 Crisis:

• Aircraft operated above 70,000 feet
• Soviet missile struck near Sverdlovsk
• Francis Gary Powers survived ejection
• Soviet authorities captured Powers
• Incident created international crisis

On May 1, 1960, all that would change. In 1960, a U-2 taken down by a surface-to-air missile in the Soviet Union was piloted by Francis Gary Powers of the CIA. Powers was able to escape and survive, but was taken prisoner by the Soviet authorities. The wreckage of the aircraft was also recovered, giving the Soviet Union tangible proof of the U.S. reconnaissance mission.

The incident escalated into a global crisis. American officials tried to claim the aircraft was a weather plane that had lost its way, but the USSR publicized Powers’ survival and that most of the aircraft had been recovered. It did much to erode the faith of the American public, it was a setback to the Eisenhower-Khrushchev summit, and it spelled the end of U-2 flights over the USSR.

7. RB-29

The RB-29 Superfortress was a reconnaissance type of the well-known B-29 bomber. Reconnaissance versions were fitted with cameras and electronic equipment to obtain information about the military activity, rather than used mainly in the bombing role. These aircraft were used during the early Cold War to keep an eye on borders, gather radar transmissions and take photos of key installations.

The Vladivostok Interception:

• Mission operated near Vladivostok
• Soviet La-11 fighters intercepted aircraft
• Aircraft entered Soviet airspace
• 23mm cannon fire caused damage
• Only one crew member survived

An RB-29 was flown on a mission near Vladivostok on 7 October 1952, which was officially called a weather reconnaissance mission. At close range the plane was picked up by two La-11 Soviet fighters from the Pacific Fleet Air Force and instructed to turn around. Things began to get more serious when the American plane kept its course and flew into Soviet territory.

The Soviet pilots fired their 23mm cannons at the RB-29, which was heavily damaged. The plane finally crashed into the Sea of Japan, and only one crew member survived. An American ship then came to her rescue. This incident was a reflection of the uncertainty of reconnaissance and weather flights during the early Cold War when planes flew near Soviet country were always in danger of interception and attack.

8. C-118 Liftmaster

The Douglas DC-118 “Liftmaster” was a military transport from the Douglas DC-6 series. The C-118 was an unarmed transport that carried personnel and equipment long distances, as opposed to reconnaissance aircraft specially engineered to provide intelligence. This role was very different from that of aircraft like the U-2 or RB-47, but its crews were also potentially in serious danger when they flew too close to Soviet controlled areas.

Forced Landing After Soviet Attack:

• Transport flew toward Karachi
• Soviet radar detected aircraft
• MiG-17 fighters intercepted it
• Crew made emergency landing
• Everyone aboard survived

A C-118 was en route from Wiesbaden, West Germany, to Karachi, Pakistan on June 27, 1958. Soviet radar picked up the plane as it came close to Soviet Armenia, and MiG-17 fighters were scrambled to intercept the plane. Soviet troops considered the position of the aircraft to be an infringement on the territory and its location to be in international airspace and therefore a justification for action.

The Soviet fighters opened fire on the transport, and the pilot and crew of the plane made a forced landing in a field outside of Kars, Turkey. Incredibly, all on board survived. The wreckage of the aircraft was finally returned in parts and the crew was safely repatriated through diplomatic channels. The episode also brought to the forefront the Cold War issue of uncertainty regarding airspace boundaries, especially in areas where national borders and military zones were closely guarded.

9. RB-66C Destroyer

The RB-66C Destroyer was not a bomber, but rather a high-speed electronic reconnaissance aircraft. It was equipped with radar, surveillance gear, and used to monitor air defense systems and locate enemy radar installations. For missions such as these, aircraft and crews had to fly near heavily defended regions, making them critical to the success of American intelligence operations.

The Gardelegen Incident:

• Aircraft reportedly entered restricted airspace
• Soviet ground stations detected aircraft
• MiG-21 fighters were dispatched
• Crew members successfully ejected
• Captured airmen were later released

An RB-66C was on a reconnaissance mission when it allegedly strayed into Soviet controlled airspace near Gardelegen, East Germany on March 10, 1964. The plane was spotted by Soviet ground based radar stations and Soviet fighters were sent up. The MiG-21s then fired on the American planes.

The three crewmen have made it safely to the surface, but the RB-66C crashed in East Germany. They were arrested and interrogated by the East German government, but the period of suffering was not as long as for some other instances of the Cold War. They were released after 11 days, thanks to diplomatic negotiations. Again the results of these engagements might hinge on seconds, height and ability of the aircraft crew to escape in time before the plane was destroyed.

10. C-130 Hercules

The C-130 Hercules was first introduced to the U.S. military in 1956 and has since become one of the most significant transport aircraft in the history of American aviation. It was mainly a logistics vehicle; some models were also used for reconnaissance and surveillance. Because of the versatility of the aircraft, it could be deployed for far more than routine cargo flights even near the sensitive international borders.

The 1958 Armenian Airspace Shootdown:

• Reconnaissance-configured C-130 crossed border
• Soviet radar detected aircraft
• MiG-17 fighters intercepted aircraft
• All 17 crew members died
• Incident remained painful Cold War episode

A C-130A in reconnaissance configuration, flying near the Turkish border, entered Soviet Armenian airspace on September 2nd, 1958. They were spotted about 17 miles into Soviet territory by Soviet radar and MiG-17 fighters were launched. The interceptors downed the C-130 close to the village of Sasnashen.

The C-130 incident was a stark reminder that a reconnaissance mission might be very dangerous, even for the C-130, which was primarily used for transport. The area was one that was already under Soviet security watch, and the border crossing fired back. With the death of all 17 crew members, it was one of the deadliest Cold War shootdowns involving U.S. crew members.
