Russia has repeatedly denied any involvement in the destruction of the Malaysia Airlines flight shot down by a Russian missile over eastern Ukraine in 2014, killing 298 passengers and crew.
The report on Malaysia Airlines Flight 370, which vanished in 2014, found that a flight simulator at the pilot's home contained a route similar to the one investigators think the missing plane took.
When the jet returned to the airport, the suspect was already tied up. Police took him away — but they left the device he had held on the plane, along with the passengers, for 90 minutes.
Three years after MH Flight 370 disappeared from radar, Malaysia's national carrier says it will use satellites to track its planes at all times and that it will be the first airline to do so.
In March 2014, the flight vanished from radar with 239 people on board. Search crews have examined more than 45,000 square miles of the Indian Ocean, to no avail.
A new analysis of existing data suggests that MH370, which vanished in March 2014, might have gone down to the north of the existing search area in the Indian Ocean.
Of debris that has turned up, officials note that "none of it had provided information that positively identified the precise location of the aircraft."
As investigations continue into the downing of Malaysia Airlines Flight 17 over eastern Ukraine two years ago, the Kremlin has dismissed a new report that directly implicates the Russian military.
Air crash investigators have looked at debris found on the coast of Mozambique, and say it "almost certainly" came from the missing Malaysia Airlines plane.
French authorities say they know "with certitude" that a piece of debris found in July is from the Malaysia Airlines plane. The reason why the Boeing 777 disappeared remains a mystery.
Malaysian officials say a wing fragment found on Reunion Island is from the missing plane; French investigators say they're almost — but not quite — certain.
A source tells NPR a piece of wing found on an island appears to be from a large passenger plane. Other media say sources link it to a Boeing 777 like the Malaysian jet that disappeared last year.
It said the battery had expired 15 months prior to the Malaysia airliner's disappearance. The report also said there was no evidence the plane's crew acted abnormally ahead of the flight.
After Malaysia Airlines Flight MH370 vanished over the Indian Ocean, air safety authorities have argued for more frequent contact in order to better locate aircraft in the event of tragedy.
