There are clearly slow-speed pushers with ballistic chutes, as I
think you knew based on some stuff I snipped. On a Long-Eze I'd be
more concerned about canopy/shroud strength and maximum deployment
speed rather than prop fouling. I'd bet adding a chute to a
fast cruiser where it wasn't designed in from the start would
either add a significant amount of weight in terms of additional structure

I'd been wondering the same. On hang-gliders the parachute is
attached to the pilot and not to the aircraft, so provided the pilot can
stand the opening shock it doesn't matter what happens to the wing - I
wonder if the answer is to attach the bridle to the pilot's seat rather
than the airframe.

Someone in Russia (Zvezda?) was marketing a lightweight
ejection seat for GA a while back. Dunno if they're
still around.

The Air Force and Navy do that. They call it an ejection seat. :-)
