'Logic explains most UFO sightings'

In most cases....

most can be explained....

Yada yada yada.....yes we've heard all of this before, and to be honest, most UFOlogists would concur....

Thing is, it's the minority that interests us....the ones seen by experienced observers, credible witnesses, and peaking military interest, that one gets excited about.... Until logic can explain ALL sightings, such as a craft executing a 90 degree arc and shooting straight up at multiple MACH speeds, etc....then we're left wondering just what the hell was that thing?
