Despite the fanfare of January 31, there are still two more Boeing 747 deliveries pending -- and they're by no means ordinary.
These are the two new US presidential planes, which are technically called VC-25, even if they're popularly referred to as "Air Force One" (a call sign that is only used when the US President is on board).
These two planes have already been built, having originally been destined for Russian airline Transaero, which went bankrupt in 2015. The two future Air Force Ones are currently undergoing an extensive program of modifications to prepare them for presidential service.
