Indian Ocean Debris Believed To Come From Missing Flight MH370
McGruber writes that air crash investigators, though maintaining that it is "too early to tell" with certainty, have 'a high degree of confidence' that a piece of wreckage found on the Indian Ocean island of La Reunion is from a Boeing 777 — the same model as the doomed MH370 which disappeared in March 2014. Investigators will need to examine closely the wreckage to link it to MH370, but MH370 was the only Boeing 777 ever lost over water.
But lots of JETsam.
With that amount of damage, I'd say it must have come from a United flight.
Have gnu, will travel.
