        One of the scariest videos on YouTube was recorded by the nose-cone camera of a fighter jet asit was taking off. 26 The pilot spends an agonizing 30 seconds or so trying to regain control,before issuing the order to eject, after which the viewer is treated to a shot of the onrushing groundbefore the screen goes blank.         Bird strikes are a problem—sometimes a fatal one—for military and civil aviation alike.America’s Federal Administration reports that there are about 10,000 such strikes a year to thecountry’s non-military aircraft, costing more than $957 million in damage and delays. 27         Moreover, though relatively few people have been killed in accidents caused by bird strikes, thepotential for something horrible to happen is real—as was shown by one of the most famous strikesof recent years. 28 The passengers were saved only by the skill of the pilot, Chelsley Sullenberger,who managed to ditch the plane safely in the Hudson river.         At the moment, attempts to deal with the problem mostly involve efforts to cull flocks of thelarger species—geese in particular—in the vicinity of airports, and also the use of bird scarers to tryto drive off those actually sitting near runways. 29 There may, however, be a better way. For adecade or more the air forces of several countries have used radar to track birds which might threatentheir aircraft. 30 If they work, the old methods of trying to scare birds away, or cull them, can beabandoned. --------------------------------------------------
