An Ethiopian Airlines 787 Dreamliner has suffered an “internal fire” while sitting empty on the tarmac at Heathrow Airport. All reports on this fire are being issued in very guarded language as if no one wants to say the word batteries. Boeing says it has people on the ground and they are trying to get to the bottom of the fire. The Dreamliner was grounded this year because of the fire potential in the newly-designed lithium batteries designed to reduce weight. In what some consider a scandalous mistake, Boeing and other certified the batteries as safe when in fact they were very prone to fire. There has since been adjustments made but this incident, if it is a battery fire, will cause great concern for the safety of the 787.
