The CF-18 mishap pilot account confirms the obvious --
aircraft stall under controlled (but high risk) conditions.
No mention of any aircraft malfunctions, compressor-stalls, bird-strikes, cockpit warning lights/audio, etc.
Brief mention of turbulence, which the pilot considered commonplace under those circumstances.
Slow/Low pass at 115 knots & 25 degrees leaves no margin for error at that altitude. Normal F-18 Final Approach Speed is ~130 Knots.
Pilot seems bewildered as to why his aircraft fell out of the sky. He thinks he was flying at 115 Knots... perhaps that was the problem -- it would only take a very brief pilot distraction inside/outside the cockpit to drop to stall speed.

95 % of this video/interview focused on the ejection/pilot health... with little discussion on accident cause. Obviously a staged public-relations event by the RCAF PR office.
