Not only that, but during WW2, pilots from ALL sides of the war were claiming to see things in the sky that shouldn't actually be there.

So if there was some government BS, then how did both the Japanese and Germans confirm the same thing the Allies were seeing?

Sightings occurred in November 1944, when pilots flying over Western Europe by night reported seeing fast-moving round glowing objects following their aircraft. The objects were variously described as fiery, and glowing red, white, or orange. Some pilots described them as resembling Christmas-tree lights and reported that they seemed to toy with the aircraft, making wild turns before simply vanishing. Pilots and aircrew reported that the objects flew formation with their aircraft and behaved as if they were under intelligent control, but never displayed hostile behavior. However, they could not be outmaneuvered or shot down. The phenomenon was so widespread that the lights earned a name – in the European Theater of Operations they were often called "Kraut fireballs", but for the most part called "foo fighters". The military took the sightings seriously, suspecting that the mysterious sightings might be secret German weapons, but further investigation revealed that German and Japanese pilots had reported similar sightings.[9]

And notice the description of the UFO's are consistent with all the footage we have so far. Fast moving colored objects that can vanish and then suddenly reappear at anytime.
