Joking aside, if your straps were loose enough that you could slump
forward, that *would* affect your CG which would in turn affect your

There's another issue that I just thought of that I don't think anyone has
mentioned yet, though. Won't you get into a graveyard (bad terminology for
this scenario, as you're already dead) spiral? After all, if you could
stay straight and level just by taking your hands off the controls you
wouldn't need to fear IMC with no gyroscopic instruments. So it seems that
if you start high enough, the correct answer to this question would be
whatever the terminal velocity of your fuselage is without its wings. Am I
off base here?

You fly until gassless, stall, nose down, then descend too rapidly,
striking the ground with the wings ripped off. Works for me.
