If the regime is planning on sending fighters to Ukraine, they would probably come from the boneyard at Davis-Monthan AFB. I wonder if anyone is seeing increased air traffic out there? If those planes are being brought out of mothballs, they would have to be flown out of there. That would be noticed, even if you can’t see inside.
Unless they are stupid or evil enough to send our front line fighters.
I’ll have to start following that military aircraft guy again - forgot his name, but I think I have a link to it on my PC.
