"Smart" bombs are getting smarter all the time. The ones we used in the 1970s took two planes to deliver- - - -one to paint the target with a laser, and another to actually drop the bomb to home in on the laser signal. Hanoi used to surround military targets with high rise apartment houses, and our guys had to thread the needle between them to get a good hit. Talk about an increased pucker factor for the laser guy!
