Greetings all.  I'm new here and hello to everyone.  I'm not building 
but looking for a 320/360 to buy.  Any leads anyone ?

As for the idea to open a door or window before a crash, years ago, in 
the 70's, I worked with a Vietnam Vet that was involved in safety and 
crash investigation of all of whatever the Army could fly and crash.  
Many, but not all of his investigation took place in Viet Nam.  We were 
talking one day about the emergency procedures for an off airport 
landing and I mentioned the prop the door open training that I had 
received and how easy it was to prop open the door on a Cessna.  Unlatch 
the door, push it out and then rotate the handle to latch which now kept 
the door from latching unless the handle moved.

He told me that consistently in all of their investigations, an open 
door compromises structural integrity and results in far greater damage 
to the craft and injuries to the occupants.  Based on the 
investigations, the Army directive was to "close/keep closed"  any 
doors.  Many of the investigations were on Huey's and they have large 
doors.  I can see that the removal of the hatch area as a structural 
component of a Lancair Legacy type compromises a very large section of 
the fuselage.  As usual your mileage may vary.
