Cause of Boeing fire identified

British aviation investigators have identified an emergency beacon made by Honeywell International as a likely source of last week’s blaze on a Boeing 787 Dreamliner and called for it to be turned off, spurring a rally in Boeing shares by relieved investors. Boeing said the beacon could be removed in about an hour from its newest model plane. Shares in Boeing closed 2.7 per cent higher at $107.63 last night, near the high of $108.15 reached a week ago before the fire.
