Bit off gaffa tape and a lick of paint and we could solve the helicopter shortage over in Afganistan with they ex American chins ;-)
I believe Boeing looked at them but they were to far gone believe it or not
In approximately 1996, 66-19082 was rediscovered resting at Tan Son Nhut Air Base, near Saigon, in Vietnam. A Boeing team conducted an evaluation of the airframe, along with another unidentified CH-47A, for possible inclusion into a rebuild program, but found the aircraft too far corroded to be useful. As of 1996, the last known location of 66-19082 was at Tan Son Nhut Air Base, near Saigon, Vietnam. Aircraft status: Not flyable.
