You've created this craft.. that is for urban recon etc.. thing is you dont want other nations to know it.. so how to test it..
Do it in a public place.. make it look like a ufo event..
Say you have no aircraft in the area.. deny it all.. and here you go.. UFO nuts jump on the band wagon.. Strange hovering lights seen above blah blah blah town..
you've successfully tested your craft.. right in front of joe public.. who does not think it can be man made..
Secret is safe.. cover story is done without you having to do anything at all..
I dont agree.
if its the best way to keep it a secret then how comes many people think UFOs are 'secret military craft'?? kind of proves that it doesnt work IMO
