what is it?

The Yakovlev Yak-42 (Russian: Яковлев Як-42; NATO reporting name: "Clobber") is a 100–120-seat three-engined mid-range passenger jet developed in the mid-1970s to replace the obsolete Tupolev Tu-134. It was the first airliner produced in the Soviet Union to be powered by modern high-bypass turbofan engines.
