Right, then...

So a building that I work in is in the flight path of Moffett Field. I’m walking in and I hear a large jet, which is odd: Normally they either have choppers or C-130's doing touch-and-go’s, or it’s Sergei Brin’s Gulfstream, or something. But this was big. I look up and it’s a large twin-engine jet - co worker said it was a 777, but I can’t plane spot that well - with United States of America livery...just like AF1, but it wasn’t a 747 (despite not being a good plane spotter, I know what a 747 looks like). So, any read on what it could be? AF2? But wouldn’t that be announced on the news and the roads closed and such?
