I most certainly learned, next time it won't be an emergency' i'll just leave it. But its prompted me to slow down assess and read the POH next time rather than leaping to what i think is the fix.
Jamair that was a King Air ''Aunty Helen'' was on. I know a crewman who was around at the time. Apparently her close protect squad guy used his telescopic baton to secure the door, not sure how, by the straps maybe? apparently they landed with the door still ajar at the intended destination.
Speaking of gliders i have had a K-13 canopy snap open on me while in the very early ground run of a winch launch. i pulled the release and having become airborne by this time did a gentle decent and landed well ahead - luckily it was Lasham with its long runway...
After that i always pushed on the canopy firmly before taking up slack,
