The first of two former Delta Air Lines McDonnell Douglas MD-90-30 aircraft left storage in Victorville, California early July 21 on a short flight to nearby Palmdale where the aircraft will be sliced and diced to become Boeing’s Transonic Truss-Braced Wing configured X-66A. TAC first identified N930TB (tango bravo for truss-braced) in March as the lead donor aircraft for the Sustainable Flight Demonstrator program.
Boeing owns a second, N931TB, that will transformed into the new ultra-high aspect ratio winged test aircraft for the NASA test program that begins in 2028. Eventually the X-66A will test CFM’s Open Fan Rise engine after the first phase of evaluations are complete.
