Yesterday my son-in-law and his family were returning from a trip to England. The flight was American Airlines 87, and we were tracking the first leg on FlightAware, which was London to Chicago. Mid-flight, the plane turned and began a descent into Keflavik, Iceland: They’re still stuck there, of course missing their connecting flight from Chicago to Knoxville. Just found out their next scheduled departure from Keflavik was cancelled. “Time to spare…” The pilots said the reason for the diversion was the plane “lost its navigational capabilities”. That seems odd to me - wouldn’t planes on transatlantic flights have multiple redundant means of navigation? I only half joked they should have offered the pilots their iPhones to navigate with. Of course, something may have been lost in translation, but how does this explanation sound to the airline types here?
