The airplane fragment found on the Indian Ocean island of Reunion is from a Boeing 777 — the same as missing Malaysian Airlines Flight MH370 — sources told NBC News on Thursday.
The barnacle-covered plane piece was found by a crew cleaning the coastline Wednesday. On it was a number — 657-BB — which sources said is attached to a Boeing 777.
MH370, which disappeared in March 2014, is the only 777 known to be missing anywhere in the world.
