Surprise is also difficult because U.S. planes would be detected as they neared Iran. Even though the Iranian air force's capability has deteriorated dramatically in the past year, its radar units might well be able to pick up approaching aircraft. In any event, the Soviets would surely spot the American planes. Observed Zumwalt: "The Russians would alert the Iranians just to cause us trouble." There would also be the possibility, though not great, that U.S. planes could be shot down by Iranian antiaircraft missiles-all of course supplied...
...bomber. This would enable these FB-111s to fly into the U.S.S.R. faster (at 740 m.p.h., vs. 450 for the B-52) and more safely at low altitudes. The FB-111 would be more difficult for the Soviets to detect, hi part because it shows up as a smaller radar image than the B-52. What might prevent Allen's project from taking off is its price tag: $6 billion...
...most elusive manned aircraft in existence. So fast does the sophisticated spy plane move that when a pilot starts a 180° turn over Cuba, he completes it halfway to Bermuda. By emitting ECM, or electronic countermeasure radio frequency signals, the Blackbird can efface its image from watching radar screens...
...monitor military targets anywhere in the world. Most important are the Blackbird's ELINT-electronic intelligence-gathering functions that are also known as "ferreting." SR-71s can detect hidden objectives by interpreting electronic signals at extremely high altitudes. In addition, Blackbirds carry a long-range, side-looking radar (SLAR) that can spy deep into foreign countries without actually crossing their frontiers...
...have been the first to shout "hello" into a telephone mouthpiece. His one discovery in basic science-the "Edison effect," the emission of electrons from a heated electric conductor-led eventually to the creation of the electronics industry. which has given the world radio, television, computers, radar and other marvels. Indeed, Edison's inventions are literally too numerous to mention. He set and retains the record for U.S. patents held by an individual, a staggering...
