AF1 is the call sign for ANY plane POTUS is on. That being said, the "official" AF1 is a 747-200 (the top pic). The bottom pic is not what is used for AF1, and looks more like the 707 from the Nixon--> GWB era. Accodring to WhiteHouse.gov, there are 2 different "Air Force 1" planes, and both are Boeing 747-200B. PLUS, BIDEN is nowhere to be seen. I wouldn't be surprised if that was a stock photo or stock footage. https://www.whitehouse.gov/about-the-white-house/the-grounds/air-force-one/
