No, Chris, they were the ones in which the 'Big Tamale' was stored - and its late flight crew preserved in gloop.
I did have a little fun before the F-117 was declassified by making up some spoof 'zaps' using cut, paste, snopake and xerox. These showed a picture of the alleged 'F-19', a Lockheed logo and '???th TFW, Tonopah AFB' written on them. I made quite a few (just photocopied them) and distributed them covertly around various places, such as stuck under the perspex of the nav planning section at Andrews AFB, inside the Dash One of the U-2 at Patrick AFB, hidden in various USAF planning documents at other US bases etc etc. You could also have fun with those USAF self-carboning flight plans by pressing the aircraft type 'F-19' (and later 'Aurora') through the top copy....
Later heard that this had caused consternation in some quarters! But the zaps kept re-appearing; someone told me they'd seen on on the cockpit door of Concorde!
