A plane sitting by the gate catches fire and you comment "no big deal"? You are joking, right?
Burning plastic is hazzadous to any fire fighter's health even in open spaces. One man was taken to hospital, according the report. Fire fighters may not want to go near a flaming 787 without full protective gear. How about passengers and crew safety? They are trapped in a capsule and will have to breathe fumes as they try to escape.
