The 5th episode of MH-17 Inquiry has just been released, and it looks like a blockbuster.

Contrary to all speculation heretofore that Malaysian airlines flight MH-17 might have been shot down by a SU-25 - an aircraft primarily intended for the ground attack role - the producers of this documentary advance a different theory.

The MiG-29 has the speed, operational ceiling, and armament to shoot down a Boeing 777. And Ukraine has plenty of the fighters in its inventory.
