Theres a known bug with Loyal, that causes him to vanish and reappear somewhere around Black Mountain. According to his wikia page he can be found between Tabithas Shack and Hidden Valley. In the worst case Loyal's stuck inside the landscape and thus unreacheble. --Warb10 20:58, July 5, 2012 (UTC)

You might have already checked this, but after you raise the B-29 up out of Lake Mead, Loyal will begin working on it in another part of the main Hangar at Nellis. Look for him on the other side of the airplane fuselage parts, in about the middle of the hangar, standing at a workbench.
Hello again. Once the parts of the plane from Lake Mead start showing up, Loyal moves to another part of the same hangar-- the same building he is always in. Just walk around the plane parts until you see a workbench-- he often spends time there. Just to repeat, the hangar is the same building he is always in. One other thought-- have you tried looking for Loyal in his house when he goes to sleep at night? His house is in the row of Quonset huts that have the Nellis Workshop and the Boomer Musuem in them. Good luck!
