I really hate to admit it, but, to my great chagrin I once departure stalled
and crashed a rear-engine ultralight. Think of a Quicksilver, except the
engine was under the wing. Well, it didn't "tear loose" but rather went
right over my head. A friend and a passerby together elevated the tangled
mass of tubing enough for me to crawl out from under it. Amazing how hard it
is to release a seat belt when your body is dangling from it...
