A team of investigators led by the Dutch Safety Board said in a report Wednesday there's "no evidence" that Malaysia Airlines Flight 17's cockpit voice recorders had been manipulated after the crash.
The Dutch Safety Board requested that the Air Accident Investigation Branch of the United Kingdom (AAIB) analyze Flight 17's data recorders, also known as "black boxes" despite their typically bright orange color.
Many observers were concerned the black boxes -- which include a cockpit voice recorder as well as a flight data recorder -- were somehow tampered with by pro-Russia Ukrainian rebels who control the scene of the crash. Speculation that said rebels may have been responsible for shooting down Flight 17, some say, was a potential incentive for the rebels to damage or destroy the devices to hinder an investigation.
Malaysia Airlines Flight 17, a Boeing 777, crashed July 17 in eastern Ukraine, killing all 298 on board.
