Hanging out in Moab, UT and came across this on the ramp used by the local lawn dart outfit. It's about as basic as can be - high lift wing and no concession to speed. There's not a flush rivet on it. Sure looks rugged.
Something I've never had any desire to do. I don't want to jump out of a perfectly good airplane or even a bad one, unless it was on fire.
@Mike Newman may have heard of this company. It's the only one I've ever seen.
