What does it take to sell a Russian jet to a Russian airline? A cockpit that doesn’t need a three-person crew, but the Tu-214‘s manufacturer can’t promise that.

A deal between S7 Airlines and the State Transport Leasing Company (GTLK) for up to 100 Tu-214 passenger jets could collapse — or be scaled back to a minimum number of aircraft — according to the Russian business daily Kommersant, which cited sources in the aviation industry.
