I haven’t seen any other aircraft other than the 707/757/747/G3’s in that livery but that doesn’t mean that there aren’t others I guess. I remember seeing other biz jets and turboprops used by the government but I can’t remember if any of them were painted as such.

I’ve only seen high up military officials and government folks use that fleet. The president uses the 747 as his main ride and would probably only use something smaller if the destination had operational limitations (too small of a runway) but that’s something I’ve never seen done. The VP uses the 757 primarily. The only reason I can see the VP or Secretary of Defense needing such a large aircraft is not for themselves but because of the large group that follows them around. Throw in a handful of reporters, support staff, crew members and other odds and ends of PR stuff and they can fill up a 757 pretty quickly.

Just FYI, any USAF aircraft that the President flies in is called Air Force 1. The 747 (VC-25a) is only called that when he’s on board and uses another generic call sign when he’s not. If he were to fly in a F-16, that aircraft would be called Air Force 1. The same holds true for the other branches of the service. When he flew onto the aircraft carrier last year the Navy aircraft used the callsign Navy 1. The flight on the Marine helicopter to the White House is referred to Marine 1. The VP gets the Air Force/Marine/Navy/etc. 2 callsign. There is a callsign if either were to fly a civilian aircraft but I can’t remember what it is. Someone told me about it years ago but have since forgotten it.

Looking forward to the pics. 😎
