Hanging from their bellies are 1,000-lb. platforms with $3.5 million in sophisticated radar equipment similar to that carried by AWACS planes. Though the balloons have been known to come unleashed (one wanderer had to be shot down in 1981), airborne radar is still more efficient than the ground version. It can pick up traffic in what Customs agents call "Smugglers' Alley," a wide band of Caribbean sky that is virtually invisible to land-based radar dishes because the curvature of the earth prevents them from detecting objects close...

Built in the 1950s, the DEW line radars are now virtual museum pieces. In their place, the U.S. and Canada will install 13 manned long-range radar stations and 39 automated short-range radars capable of detecting and tracking a new generation of low-flying Soviet bombers and even newer Soviet...
