Now operating (for a little while longer) in this part of the world.
I have always said, the day I come to an airport to position & I see a former CCCP machine awaiting me on the apron , is the day I ask for a rail ticket or a rental voucher ( & a long drive) with Hertz.
I have yet to see any evidence that I am not applying common sense here.
Not Russian bashing, but jeez, just look at the statistics, for 1 year/2 years/ whatever period you choose.
Whether by bad operation/design/maintenance/piloting technique. . . death traps.
Sorry to be so blunt, and condolences for anyone whose Company/Team Boss books you on one of these things.
Me, I lose my job in preference to climbing aboard, 100% sure.
