Nearly one week ago, a fire erupted inside a parked Ethiopian Airlines Boeing 787 at London's Heathrow Airport. Thursday, the British Air Investigation Branch issued a bulletin urging the deactivation of an emergency transmitter on all 787s. The British investigators stopped just short of blaming the Emergency Locator Transmitter for the fire. But they did recommend that the Federal Aviation Administration order the deactivation of beacons on 787s under FAA authority. Melissa Block talks with NPR's Wendy Kaufman.
