Free plans? Open source plans?

When you get right down to it....the aviation industry has been open
source since it began. All the advancements in aviation design have
been largely improvements on prior designs. Hell, even Rutans designs
are throwbacks to the Wright Brothers.

That's putting it a bit too simplistic, don't you think?

Wright brothers didn't use a stiff outer skin of cloth and resin to carry
the loads, did they? How about a feathering tail on a spaceship?

If you want to put it that way, Leonardo Da Vinci was copied by the Wright
Brothers.
