Hey!
Why so many pings???
(Just kidding....)
;-)
Minnesota ping!
Not yet,... I got interupted by the Wed call to talk with my Dad, and Mrs SR wanting on the PC. Just getting back to more threads.
The US could surreptitiously spray paved roads with an inexpensive, but otherwise invisible chemical that when dry gives off a distinct IR signature when illuminated with IR.
For quite a while afterwards, when anyone flying over it at night hit it with an IR search beam, it would look uniform—except where someone had dug a hole and re-paved over it! There would be a big black spot.
Now guess what *that* might be.
