All 379 people made a miraculous escape from the Japan Airlines Airbus A350, which erupted into flames after colliding with the Coast Guard turboprop, as the jet landed at Haneda on Tuesday evening.

Only one of the six crew survived on the Bombardier Dash 8, which was on a mission to send aid to the country's west following Monday's deadly earthquake.

A Japan Safety Transport Board official told reporters on Wednesday, investigators had recovered the Dash 8's flight recorder, but were not sure what data could be extracted from it.

Sources say the regulator is working on the investigation with French and British agencies, where the A350 and its Rolls-Royce engines were built.

Airbus said it was sending technical advisers to help with the probe.

Separately, police say they have set up a special unit at the airport to examine the incident, but declined to comment on the report of a negligence probe.

In a statement on Tuesday, Japan Airlines said its aircraft recognized and repeated the landing permission from air traffic control before approaching and touching down.

According to air traffic control recordings, the jetliner was cleared to land just minutes before authorities say the collision took place.

In an interview on Wednesday, airline passenger Aruto Iwama recalled the horror of the crash, saying he was "scared to death."

"At landing, I felt strong shaking, and when I looked at the window, I saw sparks flying and burning. And when the plane stopped, in less than one minute, the cabin was full of smoke. Then, the cabin attendant led us out and we escaped via the slide."

Iwama credited the flight attendants for keeping control of situation, saying that despite some screaming, people were mostly calm and waited for guidance to leave the plane.

"I think that's why we were able to escape smoothly," he said.

This is the first significant accident involving the Airbus A350, Europe's premier twin-engined long-haul jet that entered service in 2015.

It comes after a U.S.-based safety group warned last month about the risk of runway collisions or so-called "incursions."

The Flight Safety Foundation had called for global action to prevent a new uptick in runway incursions as skies become more congested.
