Burt Rutan never put a NACA scoop on the Long-EZ. You would have to
go look at the old canard pushers to see who was the first to do
it, I don't remember. But it was an "aftermarket" idea that was
very widely copied. Whoever it was sold plans I think.  It became
the norm and Puffer copied it on the Cozy IV.
