The description of the plane failing to gain enough speed, running out of runway, and then striking a navigation antenna as it tried to lift off, seems reminiscent of the Melbourne tail-strike incident in 2009 involving an Emirates A340. As I recall, that even later was attributed to a typing error by the flight crew when entering the plane's estimated weight (and calculating takeoff speeds and thrust required).
Is the Yak-42 suspectible to a similar error?
