Sure I am. That's why I'm trying to sell my book "Are You Ready for Yeti?" which proves UFOS are actually Bigfoots flying kites. But you still haven't presented anything except to hawk a book that "proves" UFOs are "shhhh, super secret aircraft". So instead of complaining that nobody is buying your crappy book (and the bogus theory you base it on) Why don't you simply provide evidence of a sighting involving a super-duper-boundry-layer-secret airplane.
Cite a case. Present a photo if you're so sure of yourself.
Here's your chance to be a hero.
