The United States Air Force’s (USAF) ‘Bridge’ Air Force One is almost ready to enter service. The VC-25B interim presidential jet — a former Qatari Royal Boeing 747-8i — has officially completed its accelerated modification and flight-testing phase in Texas. The heavily modified superjumbo will now enter the paint shop to receive its Trump-backed red, white, gold and dark blue livery before its scheduled entry into service this summer.
