Finally, it should be clear that Prandtl-Glauert condensation has nothing to do with "breaking the sound barrier" and is not a Star Trek-like "burst" through Mach one. An aircraft can generate a Prandtl-Glauert condensation cloud without ever exceeding the speed of sound.
We were fairly low in altitude when the shot was taken, and heading home from the mission.
There is enough moisture over the ocean to actually cause that phenomon to happen at various speeds, not just supersonic. That is why people on the navy carriers can get that shot more often than most land-based aircraft photographers.

Exub1, I think what Sam60 is asking is valid. I'd like to include a follow-up to his questions: Why did you use what appeared to be an artist's rendering of a speculative space plane system design?
The first F-117A was delivered in 1982, and the last delivery was in the summer of 1990. . .The stealth fighter emerged from the classified world while stationed at Tonapah Airfield with an announcement by the Pentagon in November 1988 and was first shown publicly at Nellis in April 1990. The 4450th TG was deactivated in October 1989, and was reactivated as the 37th Tactical Fighter Wing.

Sorry to pipe in among the titans.
C'mon WW my man. If they are black-ops how would one gain pix?
As Wonderworld pointed out pages ago, the "public" never saw the Blackbird SR71
until after retirement.
Plus, didn't "they" do a fine job keeping F117 Stealth fighter under wraps: (8 years from delivery to public view.) I'm sure thousands were involved in it's development/production. No?

The post is not clear and the evidence of everyone's claims so far are as impressive as the best bigfoot hunters in the world!
Circumstantial evidence is evidence which requires or allows a trier of fact to make an inference which supports the truth of an assertion (in criminal law, an assertion of guilt or of absence of guilt). That is, the evidence only supports indirectly the truth of the assertion. By contrast, direct evidence supports the truth of an assertion directly—i.e., without need for any intervening inference.
Testimony that the witness saw the defendant shoot the victim gives direct evidence. A forensic scientist who testifies that ballistics proves the defendant’s firearm killed the victim gives circumstantial evidence, from which the defendant’s guilt may be inferred.
Similarly, a witness who testifies that she watched the defendant stab the victim gives direct evidence. A witness who says that she saw the defendant enter a house, that she heard screaming, and that she saw the defendant leave with a bloody knife gives circumstantial evidence.

would that tantalyzing sneakaroo pic be of the storied "black triangle" silent hovering with-a-light-at-each-corner type thingy observed, well, ALL OVER the World?

Too bad, because a project name would be very useful I'll see if I can find that badge
