Well...* I once forgot to lock the canopy of my LAK-17a before takeoff. Three
hours and forty-five minutes into the flight I was casually looking about the
cockpit and noticed that it was unlocked.* I simply moved the levers to the
"locked" position and continued the flight.

Anyone know of an occurrence of a forward hinged canopy that opening in flight?
Any possibility of this happening if the forward hinged canopy was unlocked on a
flight?


My recall of several incidents (other people's) is the unlocked front hinged
canopies stay in place until there is something that disturbs it, like turbulence,
negative G, perhaps a side slip. When disturbed, they can pop open momentarily,
but sometimes completely.
