Malaysia Airlines Flight 370, also known as MH370, mysteriously vanished three years ago Wednesday. The Boeing 777 is thought to have crashed, killing the 239 people on board, but only a few pieces of wreckage have turned up despite an exhaustive sweep of the Indian Ocean for evidence.

On the anniversary of MH370's disappearance — and amid disagreements about where investigators should be looking for evidence — take a look at all the debris that has been found so far. Then draw your own conclusions.

Wing flaperon

Found in July 2015, this nearly 9-foot piece of plane wing washed up on Reunion Island. French authorities confirmed it was from MH370 shortly afterward. "It is now possible to state with certainty that the flaperon found on July 29, 2015 corresponds to the flight MH370," NBC News reported investigators said in a statement.

Flap track fairing segment

Discovered in December 2015 by a teenager in Mozambique, this wasn't definitively linked to MH370 until April 2016. The Australian Transport Safety Bureau said at the time that it was "almost certainly" from the missing plane. "The font and color of a number stenciled on the first part conforms to that developed and used by Malaysian Airlines," Australian infrastructure and transport minister Darren Chester said, according to CNN.

Horizontal stabilizer panel segment

Confirmed at the same time the flap track fairing segment was, this from Mozambique was also "almost certainly" from MH370, according to the ATSB.

Engine cowling segment

This turned up in South Africa in March 2016 and was absolutely connected to the missing plane that May. It was "initially identified from the partial Rolls-Royce stencil," and its "panel thickness, materials and construction conformed to the applicable drawings for Boeing 777 engine cowlings," the ATSB wrote in its report. It "was a Malaysian Airlines Boeing 777 engine cowling segment, almost certainly from the aircraft registered 9M-MRO," also known as MH370.

Main cabin interior panel

The interior part of the plane showed up in Mauritius in March 2016. "There were no identifiers on the panel segment that were unique to [MH370]; however, the pattern, color and texture of the laminate was only specified by [Malaysia Airlines] for use on Boeing 747 and 777 aircraft. There is no record of the laminate being used by any other Boeing 777 customer," the ATSB wrote. It, too, was determined to be "almost certainly" from the missing plane.

Wing flap

Months passed, and then another wing part showed up on Pemba Island in Zanzibar. It was printed with serial numbers that confirmed it was from a shipment to Boeing that was later became MH370. The ATSB said in September 2016 "it was confirmed" it originated from the missing plane.

Trailing edge section

This part, discovered in Mauritius in May 2016, was the third piece to be conclusively linked to MH370, according to an October statement from Chester. "Examination revealed the presence of a unique identifying number relating to the part's construction which allowed it to be determined as definitely coming from missing Malaysia Airlines flight MH370," he added.
