Sweetman @ AvLeak Claims Plane Chasers in Texas Find Mystery Aircraft

As far as I know, this sort of thing has happened only once since 1956.

That was when British magazines started getting eyewitness accounts and grainy photos of the Lockheed U-2, then operating out of RAF Lakenheath on its first spy flights over the Soviet Union. Classified programs have been exposed in all sorts of ways since then - for example, the A-12 Blackbird was disclosed under a degree of pressure - but until the RQ-170 Sentinel was seen at Kandahar in 2007-09 there has been no such aircraft photographed before it was declassified. (And in the case of the RQ-170, the operational security people were not trying too hard.)

With that in mind, let's look at the photos taken by Steve Douglass and Dean Muskett of an aircraft seen over Amarillo on March 10.

hmmm.  I remember the doughnuts on a rope pix from the late 80s early 90s as well.
