　　Although it may sound impossible, it can‘t be ruled out. Every electrical device creates a certain amount of radiation. Portable phones, remote-control toys and other radio transmitters send out signals that can carry for kilometers, and their use on planes has long been cassette players, tape recorders and laptop computers, which make far less electromagnetic(電磁的) noise.

　　Now there is increasing proof that even these gadgets may be putting aircraft at risk. A walkman-type radio tuned to an FM station produces oscillations(振蕩) that can reach 1.5m to 3.5m-far enough, in some planes, to reach the navigation(導航) equipment in and around the cockpit (駕駛員座艙).

　　No planes have crashed and no lives have been lost-so far. But Time Magazine has got quite a few pilot reports linking a series of ―anomalies‖(異例) to a wide variety of electronic gadgets, from laptop computers to Nintendo Game Boys. In one striking example, a plane flying out of Chicago started going off course while its VOR dials became unclear and danced around. When the passenger in seat 9-D turned off his laptop, the report states, the ―panel lights immediately brightened and all navigation aids returned to normal.‖

　　The U.S. Federal Aviation Administration, pressed by pilots to punish the gadget holders on board, published an advisory late last week that Delta Airlines has already made longer its list of forbidden devices to include video playback machines and CD players.

　　With the arrival of new ―fly-by-wire‖ aircraft, which are heavily computerized and even more easily to be interfered with, passengers may have to go back to reading paperbacks and watching the in-flight movies.
