It certainly is strange and to still be finding out about additional questionable situations is pretty crazy.
With all the high altitude / satellite 🛰 footage I have often wondered if another country such as Russia have high resolution footage of what hit the Pentagon and what went down in Pennsylvania.
The Mir Space Station was deorbited in March 2001 so it wasn't up there but the International Space Station was and there was an American that took pictures of the smoke from there. Depending on it's orbit and the timing perhaps there was footage from there or some other Drone , Satellite, or Aircraft.
