In an RV-3, recently an unlatched side opening canopy
ripped off with a loud bang in flight and a friend of mine
lost his glasses with it. 100 knots in the open air
isn't fun.

He landed safely, but said it was exciting.

Katana canopies (clamshell) and side opening canopies
don't sound so great to me. Yep, the L-13 canopy
with self-latch seems pretty good, but for one seaters,
the rear-opening canopy seems like the best.
Besides, I like the vis a lot better than with
bars in the way...

I am curious about how different canopies will react to being unlatched.
The Schleicher design appears to have air pressure holding it down, at
least in the closed position. I don't know what happens if turbulence
were to bounce it up a few inches.

A friend had his DG 400 canopy open in flight, and stay open, so he had
to pull it closed. His headphones and various things flew out of the
cockpit. Fortunately, he was quite high at the time, and dealt with it
successively, but (as I recall) could not retrieve the headphones, so
the cord kept the canopy from latching after he pulled it back down.
