The biggest safety threat facing
airlines today may not be a terrorist with a gun, but the man with the portable
computer in business class. In the last 15 years, pilots have reported well over
100 incidents that could have been caused by electromagnetic interference. The
source of this interference remains unconfirmed, but increasingly, experts are
pointing the blame at portable electronic devices such as portable computers,
radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation industry, has recommended that all airlines ban such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And alth A.
