Forget the "callsign" -- show me a video of Biden getting into (or out of) the well known ("Presidential") Boeing 747-200.
I haven't found one.
I have seen one photo of a "photoshopped" Biden standing in the doorway of the Presidential Boeing 747-200.
But it's fake.
Show me video! (Or it didn't happen.)
His ears were different again!
Tell me with a guy that shuffles when walking and had a boot on his foot a month ago and 70 years old can take those steps in that video
Answer: He can't.
The splicing of it is very suspect too lol as soon as the door shuts it cuts to the plane taking off.
