The pictures, the '...eliminates the potential for fire' captions are made for public consumption I assume. So I'll be generous and surmise they mean a CABIN fire
But that would mean Boeing thinks we (pax) are all simpletons, perfectly happy to share a fuselage with a fire/potential fire of ANY kind, no matter how well they claim it's contained. That can't be right can it? They can't be so desperate to restart deliveries that they think we'd swallow that??
