That addresses the ejection, but nothing about what caused the aircraft to veer upwards and to the left then down into the ground.....
But that's what after accident investigations are for.........
Trading airspeed for altitude after an engine problem.
Pretty standard procedure. Unfortunately, the plane stalled and spun before they could get to a safe ejection altitude/location.
See post 49. It was posted by a former Snowbirds pilot who has flown the aircraft.
