Original last series MiG-21bis grey HuAF paintscheme, right from 1979 October, from the factory. I am one of the owner of the bort No 41 aircarft from the museum and actively participated in the restoration work. The paintscheme is slightly different than the officially available "HuAF grey" from the DCS, which is also correct, but based on the first, the 1975 batch MiG-21bis fleet.
In the second half of 1979, right after the MiG-23MF purchasing, the HuAF decided to refuse to get the planned second and third squadron of MiG-23ML fleet and ordered a final batch of another MiG-21bis again. The decision was partially based on the mostly MiG-21-centric HuAF point of view, while partially meet with the socialist goverment interests, since the financial difficulties were slowly gathering on the horizon. The MiG-21 was cheaper and had all the operational and maintenace background as a fully controlled circle, while the MiG-23 (which was way more capable by the way) was expensive and was available only as amount of a single squadron. This "last minute" MiG-21bis series was in between the bort No 41 to 52. Each of them were 75AP, fully grey nose ring and grey afterburner chamber externally, without the red stripes at the trailing edges. From this 12 aircrafts the first was the 41, which is available in the Aeropark museum, Ferihegy, Budapest and I am one of its owners. The aircraft made 1652 flight hours, last flight was on April 9, 1998, remained as "strategic spare" until the withdraw, year 2000. Decommision date November 24, 2000. If you want to apply other bort numbers from this one and only HuAF double digits MiG-21bis fleet in the game (the former bis fleet had four digits bort number, while the other double digits MiG-21 in the HuAF was the 1979 and the 1986 series of MiG-21UMs), four of them did crash during accidents. Two were fatal. The "52" was in air policing in the summer of 1981, fully armed with a non-experienced young pilot (it was his first armed takeoff), ordered to intercept a low level, highly maneuvering Cessna in a quite turbulent weather over small hills, close to the state border when the airplane just stalled and falled into Austrian territory. The ejection was safe, but the back injury caused the termination of the further pilot carrier. The bort No "44" crashed in 1984 right after the takeoff, because of the turbine blade crash engine shutdown. Ejection was succesful. The "45" crashed in 1988, because its pilot, a captain simply just got a complety different task right on the runway to show a low level demonstartion flight over the tactical grass airfield for some high ranking supervisors, but with no proper preparation and training. After an accidental dis-orientation, the aircraft just hit the ground at narrow angle, high speed. Bounced back to the air and falled down 300meters away. The pilot's body flew out from the closed canopy, beacuse of the extreme high impact force. The last accident with this series was with the "50" in the summer of 1991, when the airplane flew a target for the local air defence group, when suddenly hit the ground at 900km/h, in a high g turn, because of a possible g blackout.
