I agree that the canopy closed does offer more safety, especially if you roll over, hopefully you won't get crushed, but I do recall an accident a few years back where 2 people burned alive inside a Lancair and couldn't get out.

This is one of the reasons of the new, easier latching system that could easily be opened from the outside. I guess whatever your gut tells you to do in those critical seconds, is the right decision and hopefully you walk away. Matt VTAILJEFF@aol.com wrote: Mark, Excellent thoughts!
