I presume you have contacted the Phoenix Air Authorities
Or whoever is in charge of Phoenix airspace to confirm that no pilots filed a flight plan
that night? But you don't believe "my" astronomers, so what does it matter, right?
As for the military conducting secret tests of their air and spacecraft, they like nothing
better than having the masses assume they were UFOs, so they can be dismissed
by those they really don't want to find out.
Same thing with the Soviets in the 1970s with a bunch of their rocket launches.
