Don,

Some people have installed an openable rear window as a means of escape for an upside-down Legacy, or I suppose a non functioning canopy latch, and also easy access to the rear compartment.

The question some people see in this is what does it do to the plane structurally not having the window as part of the structure? Maybe it is not included as part of the structure?

or what are the effects of the wind on the structure if the window opens in high speed flight?

I guess you could reinforce the area around the window.

Is it possible to get out if your upside down? I've thought about that quite
a lot. I've thought about things like a brake failure on one side, running off
the runway finding yourself upside down watching fuel running out , then to
your horror waching it turn directly towards you after finding a "nice" low
spot right under your head. (not that it would really matter, if there was
fuel running out under the plane anywhere the results would be the same) Your
laying there helpless  you've been trying to get out but you can't cause
theres too much airplane weight against the canopy. Of course thats only if
the conopy has'nt been broken & now your head and neck are the highest thing
in the forward part of the airplane. Then you hear & feeel a puff!!!!!!!  Just
like discribed with the 2 people burning. How horrible to be unhurt in a
fairly minor accident only to burn because you can't get out! Does anybody
know of  times lancairs have gotten upside down & they have gotten out? How
did they? Did they need to lift or turn the plane over? Whats the survival
rate? Do the canopys usually crush or not?    Don
