Mysterious delta jet over Texas, a fortnight ago

[Willard Whyte]

So all this is telling me is high altitude stealth is a bit pointless if your in the contrail layer?

Apparently the B-2A has a rear facing laser, or "laser" (© Dr Evil), to detect contrails, thus enabling the computer, err... pilots, to adjust altitude.

BTW, could the pic be of a RQ-180? (See also http://www.pprune.org/military-aviat...2-retired.html )
