This is a tragic incident. 12 lives lost. My deepest sympathy and respect to their families. Also a beautiful, rare aircraft destroyed. According to planes.cz the Russian defence ministry has temporarily grounded all AN
-22 and TU
-95 (same engines) aircraft. There is only a handful of these monsters flying nowadays - I'm only aware of one for Antonov Airlines and a few for the Russian Airforce.
As for the doomed plane, according to aviaport.ru, it had been delivered in 1974, but they said something along the lines of that it has only been utilised for 10 months which I don't really understand - mis-translation perhaps. I haven't been able to track down the reg.
I hope that this incident does not put the last nail in the coffin of this remarkable, unusual, world beating machine.
