yeah, much of what they are talking about could easily be some cool spacecraft we're testing.
There are examples of crafts doing nonhuman things - climbing at impossible rates, etc.
Those could be holograms/projection weapons. One of the most effective things you can do in war is make the enemy's sky look like 10,000 planes are in the air. They'll shoot their load of anti-aircraft weapons at ghosts, and your 100 planes will have plenty of cover to hit whatever targets they'd like.
We don't know what is being flown there, and honestly, it doesn't affect us. If it's UFOs, or if its' some cool craft, or a war projection system, I could care less. It doesn't affect price of gas or mcgriddles, so it doesn't matter to me.
