By the autumn of 1986, the T10-15 aircraft, officially named the Sukhoi P-42, had been prepared for the planned record flight program. On October 27 and November 15, OKB test pilot Viktor Pugachev added eight climb-to-altitude time records to the table of world achievements in just in two flights-four absolute records for land based aircraft and four records for aircraft with takeoff weight up to 35,274 lb (16,000 kg). Pugachev climbed to 9,843 ft (3,000 m) in 15.573 seconds and to 19,685 ft (6,000 m) in 37.05 seconds.
Sukhoi P-42On March 10, 1987, and on March 23, 1988, test pilot Nikolai Sadovnikov flew the Sukhoi P-42 to 25,528 ft (9,000 m) in 44 seconds, 39,370 ft (12,000 m) in 55.2 seconds and 49,213 ft (15,000 m) in 70.329 seconds. The previous records were set on January 16, 1975, by American pilots flying the F-15 fighter. Major Roger Smith flew the aircraft to 9,843 ft (3,000 m) in 27.57 seconds, and Major Willard “Mac” MacFarlane climbed to 19,685 ft (6,000 m), 29,528 ft (9,000 m) and 39,370 ft (12,000 m) in 39.33, 48.86 and 59.38 seconds, respectively. On June 10, 1987, Sadovnikov claimed a world record for a N category level flight altitude of 63,435 ft (19,335 m).
Another record, set by Viktor Pugachev in the Sukhoi P-42, was lifting a 2,205 lb (1,000 kg) load to 49,213 ft (15,000 m) in 81.71 seconds. A total of 27 records was claimed by Sukhoi OKB test pilots Viktor Pugachev, Nikolai Sadovnikov, Evgeny Frolov and Oleg Tsoi. The record setting team of test pilots, ground service specialists and OKB designers was headed by Chief Designer Rolan Martirosov.
