More information has been released about the crash of a Royal Canadian Air Force training aircraft, near Moose Jaw, in January.
Officials say the two pilots were conducting an exercise of basic aerobatic maneuvers; during the training the student pilot reduced the thrust to idle, reducing speed and altitude.
By the time the instructor took control, the engine began to lose power and were below a safe altitude to return to CFB Moose Jaw.
The two managed to eject from the plane that crashed 40 kilometres southwest of the base, with one of them suffering minor injuries.
Investigators are trying to figure out if pilot, mechanical or training failure is to blame.
