According to Wikipedia and a recent photo tour of Davis-Monthan, the McDonnell Douglas YC-15 (72-1876) was scrapped between March and April of this year. The aircraft had been sitting in Celebrity Row. It would have been an easy tow to the Pima Air Museum!
It can be seen minus wings at the link below. It is photo 17.

The other YC-15 (72-1875) is displayed at Edwards AFB where it was left after suffering engine problems. It has been put on display next to 'Century Circle' by one of the entrance gates to the base.
