Wasn't Francis Gary Powers shot down by the Russians at an altitude of 70,000 feet in the 1950's? What technological advances have occured so that AA systems effective altitude is less? This is all just a bunch of hot air if you ask me.

Ummm...maybe the technological advance is to orbit the blimps over our own territory, which is beyond the range of AA fire from other countries? I dunno, just a guess...
