I remember when I was stationed at Nellis AFB, just before the F-117 became public they had a change of command ceremony. They had one of the A-7Ds parked on 1 side of the stage and 2 MLG tires and a NLG tire with chocks holding them in place....nothing else, just chocks and tires. Everyone on base knew that the plane existed but hardly anyone had ever seen it.
I thought that was a funny thing to do.
