Destruction of the Malaysian Boeing 777 airliner which was wrecked in air space over Donbass, the missile of the class "air-air" launched by an attack plane of Su-25 of the Air Force of Ukraine is improbable, the chief designer of an attack plane Vladimir Babak considers.

He declared that technical characteristics of the Su-25 plane allow it to rise up to the height of 11-12 kilometers, and the attack plane could reach an echelon on which Boeing (over 10 km) flied, the Censor.NET  with reference to ITAR-TASS. However rise on such height would threaten safety of pilots if to consider that the Ukrainian pilots, most likely, had earlier no similar experience.

Also the designer emphasized that the power of a military unit of the rocket of the plane is too small to destroy such large purpose as the big passenger plane. Besides, to open fire at an airliner, the attack plane had to "be attached" behind - however it would be difficult to make it as Boeing moves 100-150 km/h quicker than an attack plane. 

We will note, earlier, being guided by nature of damages of a fuselage, experts concluded that Malaysian Boeing was brought down by the rocket, allegedly, the surface-to-air type. It was confirmed also by data of "black boxes" of an airliner.
