Contract for long-lead activities for VC-25B was signed yesterday:
AF awards contract for next Air Force One > U.S. Air Force > Article Display
Congress still has to authorise the actual airframe procurement but this looks like a useful way of keeping Boeing engaged until the big-ticket contract comes through. In turn Boeing can try to keep the suppliers idling, other than those that have already bailed.
Once that's done and the VC airframes built... well, we'll see. Personally I think they'll gracefully shut-down the production line at that point, on a high note.
