Recently two pieces of debris that may have come from missing Malaysia Airlines Flight 370 were found on the coast of Mozambique.
The first piece was discovered on February 27 by American lawyer Blaine Alan Gibson on a sand bar near the town of Vilankulo (top left). Composed of fiberglass skin around an aluminum honeycomb core, and bearing the words “no step,” the piece is widely presumed to be a part of a 777 horizontal stabilizer. A fastener found attached to the part carried an identifying number that is consistent with, though not exclusive to, a 777. Soon after the find was made public Malaysia’s transport minister Liow Tiong Lai tweeted that there was a “high possibility debris found in Mozambique belongs to a B777.”
The second object was reported on March 11 by South African teenager Liam Lötter, who found it on a beach near the resort town of Xai Xai in southern Mozambique in December. Approximately a meter long, it carries the stencilled code “676EB,” which is written on the right-hand outboard flap farings of Boeing 777s. Its material, a hybrid of fiberglass and carbon fiber, is also consistent with a 777 flap fairing.
The fact that MH370 was the only Boeing 777 lost over the ocean lends weight to the supposition that both parts come from that aircraft.
The pieces’ appearance, however, is quite different from that of the first (and so far, only confirmed) piece of MH370, the plane’s right-hand flaperon, which was found on Réunion on July 29, 2015. Every edge of the flaperon, and much of its broad surface area, was encrusted with goose barnacles of the genus Lepas. The flaperon also had been settled across much of its surface by a brownish algae. Both of the recently discovered pieces are relatively free of marine growth.
This article will explore what the presence or absence of marine growth indicates about how the three pieces traveled through the ocean.
