These are of a Canadian CF-18 crash in Lethbridge, Alberta, Canada: they were sent me by a fellow who helped design the ejection system;

This info was with it. I've asked the sender for info on the pilot.

I worked and instructed technicians and aircrew on this very CF-18 Hornet Escape System in the 80's in Cold Lake and Baden.

In the pictures below (all this happens in a matter of seconds) you can see the Canopy Jettison: see the two canopy jetisson rockets), Ejection Seat Catapult, Seat Rocket Motors ( the 2 flames you can see on the bottom of the Ejection Seat, the Stablization drogue parachute (white), and the pilots main Parachute (orange and white) deploying.

CF-18 crash pictures from the Lethbridge, Alberta Canada accident.




CF-18 pictures from Lethbridge accident...

Experts say it was probably a compressor stall on #1 engine.


Incredible photos from last Friday's accident in Lethbridge.


Looks like the left engine has the nozzles open so that one either in AB or flamed out. Cool sequence of the rocket seat coming out, the canopy leaving the scene, the chute opening sequence and the separated seat falling away...technology is great! The impact photo has flame shooting out of the left engine...adds to the puzzle,




I'm guessing the right engine was flamed out and the left in AB (or reheat) as the British call it) to compensate for loss of thrust.

There would be plenty of thrust with one engine to keep the F18 in the air - if that was all that was wrong, the pilot would roll wings level and pull up. The flaps are up, so this wasn't at a critical time like take-off or landing, and there seems to be nothing missing from the airframe. My guess would be that something else catastrophic had happened (most systems in aircraft are duplicated, so a single system failure doesn't normally lead to a crash.
It could possibly be a loss of control, maybe due to Uncommanded Flight Control Movement, a failure in a control system (Stabs computer crash!), high speed stall, pilot error or something like that.

Without knowing the speed and attitude before the sequence, it is hard to say.

BTW, the left engine is the #1.

I'm fighting the urge to join in but I have a rule that I try to stick to....................

Play with aircraft all week but at the weekend...................I try not to mention or think about them at all.

(Not even wet starts, dry starts, wet farts, flap actuators, non return valves, MDC firing, seat pan firing handles, main gun sears, thrust, black boxes, red boxes, soft boxes, diff tailplanes, dissimilar metal corrosion, swept wing growth, hydraulic sequence valves, creep marks,
ground air valves, engine inlet deicing systems, flap position indicators, FWD cargo areas, AFCS accelerometers, cabin pressure inlet valves, cabin pressure outlet valves, instrument cooling systems, pack temperature sensors, liquid level transmitters, pneumatic crossbleed manifolds, nose wheel steering load levelers, command ejection override system or even flap and slat programmer control quadrants.........


.......................I just try and stay away from all that aeroplane stuff at the weekends. (I eel better now)

It happened in July 2010 (23rd) The pilot landed away from the wreckage and survived. This crash features in a couple of You Tube video's and you can see the pilot land well away from the impact.

There is another video out there (in You Tube land) of a Harrier crash landing (at Kandahar, I think) in that one the pilot stays with it as it bounces along the ground, only ejecting as the flames are alongside the cockpit. As he was carrying a fair bit of ordnance that cooks off at the end of the video, he was either mad or very brave....
