When are we gonna shoot one down? That’s the only way to prove what they are!
I like your ‘nuke it from orbit...only way to be sure’ approach. LOL.
On the other hand, lore has it that such attempts were made, resulting in downed jet fighters. One such intercept was that of an F-89 Scorpion over the Great Lakes. The fighter did not return.
Telephone linemen are all over the country, ready to observe what appears in the sky. Those fellows are called together from time to time for training or other purposes. They talk off topic as they get the chance. A lineman told me that a fellow he knows saw an F-4 Phantom being hauled out of the woods on a flatbed truck. As it moved, soldiers were in the process of pulling a tarp in place. The surfaces of the F-4 he saw looked like the hole patterns of pegboard, except black. Rumors around Fort Campbell at the time surrounded an F-4 intercept of a UFO over the "Bird Cage".
