British Airways is near the end of a test of a passenger restraint ironically called the Hugger in an effort to get tough on air rage. The Hugger was invented by retired London bobbie Roger Fuller, who was himself involved in an air rage incident in the mid-1990s. At about $300 per Hugger, Fuller is peddling the device to over 400 worldwide airlines. BA and other airlines may not implement the device, however. Flight attendants and air transport groups are more cautious concerning taking offensive actions.
