You're serious? You just placed the canopy and took off?!?!

If you were being sarcastic (:P); I was asking because a lot of people invent something to replace the '2 screw mechanism'.. for instance canopy latches. Those won't work in my opinion because in my experience the canopy is a structural part of the plane, if well attached it adds strength and in flight several forces will work on it.

If you're not being sarcastics.. everybody makes misstakes. I've seen the wings come of an edge in flight, because the pilot forgot to attach them.. he just slided them over the tube untill they were flush with the fuse and then forgot to put the screws in.. sh*t happens.
