We had three (one was a 1907 repro) opn the ramp at Dayton General South
back in 1991. Local retired USAF 0-6 has been flying his for years.
Don't
know about the most recently publicized repros, but methinks thay are not
as
rare as the TV folks would have you believe?

Less rare now than in 1991 at least.

I think the biggest issue is the engine. There aren't many reproductions of
the Wright Flyer powerplant. Substitute a relatively modern design and
power delivery ceases to be an issue.

Minor mods to the original Flyer design could result in a very flyable
aircraft that looked quite authentic, but because of its improvements
(something the Wrights were incorporating in the design after their initial
success) wouldn't come close to emulating the original. So far I've found
only two efforts where the machine is a genuine attempt to reproduce the
original Flyer, right down to its engine.
