Yikes! Just took a 787 Dreamliner to-and-from Toronto to Munich last month with Air Canada and both eight-hour flights were flawless. Something like this never crossed my mind while we were crossing the northern Atlantic. Sure hope this wasn't one of the planes we were on! What airlines did you say this was? It's really up to their safety inspections to look for signs of metal fatigue and cracking and ground any plane accordingly. Maybe in the future we'll focus more on flights that use Airbus planes.
