John,

That is exactly what I am planning. I am going to install a cam in-between the two front Canopy hinges, that will pull pins out of the two forward modified separable hinges. As for the Canopy sliding back and decapitating me, or just taking out my teeth, I plan to install a hinge on the rear of the canopy for it to pivot up and back on. Some kind of hook that you engage, or a hinge made of chain link with a pin you can put in before takeoff. I am working with a Parachute company to develop a parachute that you don't sit on, (I want comfort, and no excuses not to wear it) You will have the usual harness straps, but the Chute Pack will slide into a pocket behind the seat and down at a 45 deg angle. They said they made something similar for another plane.

no longer part of the structure."

It's a worry of mine too and, after four years of flying, I still don't
have an answer for it.  I think if you stay upright there should not be
a problem, and history, at least so far, seems to bear that out.  It's
hard to imagine anything that would jam either the hinges or the latch
mechanism.  The thing I worry about is if you flip and end up upside
down.  In that case, I suspect you are stuck inside until someone cuts
you out.  Having gone in and out of the back window a few times during
construction, I can attest to the fact that those of us who have put on
a pound or two will find it a tight fit.  Trying to get past the
openable windows would, I fear, require a physique different from mine
-- and that's assuming full functionality.  I've thought of carrying one
of those hammer thingys, a knife, a saw, pretty much everying.  I think
the best solution might be a battery powered dremmel but I have to say I
don't carry one.

Having spent last weekend getting my ICAS clearance to do rolls at
airshows, I have another thing to think about:  Is it possible to put
"pullable" pins in the canopy hinge attachment so you could bail out in
an emergency?  We were talking about the rule that you have to have a
parachute if you are dual and doing acrobatics and I pointed out that
the highest and best use of a parachute in a conventionally built Legacy
is as a seat back cushion.  A set of hinge pins would fix that in the
event of, say, a fire.  It would also give you two ways to get out after
a crash, asumming you were upright.
