Somewhere in my aged memory cells I seem to recall a story about Burt Rutan
and John Rontz collaberating to mount an engine on a sheet of plywood and
tether "flying" it to illustrate that anything will fly with the correct
AOA. I'm not finding any references on the search engines, truth or myth?

I've never seen that one, but I believe that theory was confirmed with the
video of the flying lawnmower.

Actually, the flying lawnmower has a real wing airfoil, buried under the
profile.

A flying stop sign is a valid example, though.

It is truly a flat sheet of foam board, with control surfaces and an engine.

I liked the flying Snoopy on his dog house. I can't remember who made it.

Close, but still nice.

A few weeks ago, my friend (a pilot also) stepped onto a piece of plywood
laying on his sloping roof. He then flew the plywood down to the ground.
It did not fly very well. He broke his heelbone.

I think that no matter how big an engine you put on a piece of plywood, it
will not fly very well.

He's damn lucky all he broke was his heel.

It all is in the power to weight ratio, AND the weight to wing area, and to
a degree the aspect ratio.

Of course, there are helicopters, too.

Your friend's problem was that he did not have ANY engine! <g>

This reminds me that a friend, who is an Air Force veteran, told me that
helicopters can not actually fly--they are just so damned ugly that the
earth repels them!

That's his story and he's stickin' to it.

If you're going to tether it, why bother with the plywood?

Just suspend at least one tether from above so that the prop can't
strike the ground, duct tape the proverbial brick to the engine,
and fly away.
