Ethio­pian investigators delivered the mangled orange flight data recorder to specialists at France’s civil air safety investigation authority, the Bureau d’Enquêtes et d’Analyses, or BEA, which has extensive experience analyzing crashes in Europe and around the world. They also carried a cockpit voice recorder.

Investigators from the National Transportation Safety Board, the U.S.’s independent investigative agency, as well as the Federal Aviation Administration, will add their expertise to the investigation involving the Boeing 737 MAX 8 aircraft, which was certified by FAA officials working with the American aviation giant.

Ethiopian Airlines chief executive Tewolde Gebremariam had said earlier this week that the boxes could go to the United States, but then immediately added they would more likely be sent to Europe in interests of proximity and speed.

Ethiopia’s decision to then offer them to France came just after the visit of President Emmanuel Macron, who left Ethiopia on Tuesday

Some experts have suggested that it was prudent to send the devices to Europe for examination given that the plane was built by a U.S. manufacturer

After a major airline disaster such as the one Sunday,which killed 157, investigators rush to recover the devices. They are required on all airlines around the world and are built to withstand fire, heavy impact and intense water pressure. When planes go down in the ocean, a pinger attached to the black box sends a signal that sounds like a grandfather clock ticking for about 30 days before its battery dies

Typically, experts say, it takes almost a month to provide a comprehensive analysis of a flight data recorder

The Ethio­pian Airlines devices were discovered quickly after the crash, leading some U.S. officials to hope the insights within them would help determine whether American authorities should ground the 737 MAX jets. While Ethio­pian investigators have the ability to download information from black boxes, they lacked the tools to do so in this case given the extensive damage, according to the FAA

It is unclear why it took days for the devices to be given to international investigators with suitable equipment and experience

The NTSB said it had dispatched a team of three to France to assist with downloading and analysis. The agency had already sent four investigators to Ethi­o­pia. An NTSB spokesman said declined to say if the investigators were already on the ground, nor would he comment on whether the Americans had seen and assessed the condition of the black boxes

U.S. officials say Ethio­pian authorities are taking the lead in the investigation, per international protocol, but U.S. experts have been cooperating with their counterparts from the onset

Because the 737 Max 8 was built in the U.S., the NTSB can send an accredited representative to the investigation. The U.S. delegation of experts also includes technical advisers from FAA, Boeing and GE/Safran, the manufacturer of the engines

“This is not our investigation. This is an Ethiopian investigation,” NTSB spokesman Eric Weiss said. “We will be helping to download and analyze the flight data recorder and the cockpit voice recorder.”

The data in the black boxes could help investigators determine if Sunday’s crash is related to an automated feature on the aircraft, hundreds of which were flown around the world until countries, led by China, began barring them from flying in their airspace Monday

FAA officials said Wednesday that new satellite tracking data and new physical evidence from the wreckage of the crash in Ethiopia showed similarities to the crash in Indonesia, leading the agency to ground both the 737 Max 8 and the Max 9, another aircraft in the series. The U.S. decision came after much of the world had already grounded the plane

Some experts have pointed to parallels between the two crashes. Both involved relatively new 737 Max 8s. Both crashed shortly after takeoff. The two jets also struggled to gain altitude and appeared to ascend and descend several times before crashing

But they say it is too early to determine whether the same malfunctioning sensor, coupled with an automated response from the aircraft’s software that stymied the pilots’ ability to control the Lion Air flight, contributed to the downing of the Ethiopian Airlines plane. Investigators have not determined a final cause of the Lion Air crash

In Ethiopia, the investigation continued Thursday

The NTSB investigators dispatched to France will work in coordination with those on the ground in Addis Ababa, the agency said

The NTSB team is smaller than a typical go-team that would be sent to a crash on U.S. soil, which could consist of a dozen to 25 people

Black boxes have helped investigators examine many crashes and have led to significant improvements in airplane safety and pilot training. Some U.S. airlines began to use flight data recorders in the late 1950s and the recorders quickly caught on in other countries

This is a developing story.
