For the 1993 Air Tattoo, the Russians had sent two Mikoyan MiG-29 Fulcrum fighter jets, especially decked out for the display circuit in the colours of blue, yellow, and black.
The pilots were two of the best civilian test pilots the Russians had at the time, Sergey Tresvyatsky and Alexander Beschastnov from the Gromov Flight Research Institute at Zhukovsky (near Moscow). Tresvyatsky was also a cosmonaut.
During the final stages of the demo flight at Fairford, both pilots were expected to position themselves at diametrically opposed points on a loop and chase each other around it. Unfortunately, it did not work out that way.
At about 1,000 feet (300 meters), a mid-air collision occurred due to a combination of adverse weather conditions, faulty design of the flight plan (parallel loop), and human pilot error.
Both aircraft were destroyed, with Tresvyatsky’s jet losing a wing and Beschastnov’s jet effectively broken in two.
Both pilots reacted instantaneously and ejected almost immediately as if automatically, which further confirmed the Western world's notion of the “Russian robotic pilot”.
Both pilots landed safely on parachutes, and both crippled jets crashed in unpopulated areas. Nobody was injured.
Western aviation experts were amazed at how the ejection seats had successfully handled the complex ejection situations that the two Russian pilots had encountered.
Tresvyatsky had ejected while the airplane was inverted (aka “punch-down”), and Beschastnov had ejected while his MiG-29 was in a vortex (simultaneously spinning on all its three axes of movement — vertical, lateral, horizontal).
Aside from the superb and amazing fast reactions of both pilots, recognition eventually set in that it was a truly remarkable product that saved the two Russian pilots' lives — the Zvezda K-36D ejection seat.
