One of the pilots flying the Brazilian plane that crashed last week and killed everyone on board sounded the alarm over the impending doom a minute before it went down.

A transcript from the cockpit’s “black box” voice recorder revealed that pilots noticed a steep drop in altitude leading up to the crash, local Brazilian outlet TV Globo reported on Wednesday, citing unnamed sources involved in the crash probe.

At one point, the co-pilot asked the pilot what was going on and said the plane needed “more power,” according to the transcript which covers two hours of audio.

The new revelation comes as investigators are still trying to figure out why the plane, an ATR-72-500 operated by Voepass, crashed, killing all 62 passengers and crew on it.

The plane was flying to Sao Paulo from Cascavel when it went down in Vinhedo Friday afternoon local time.

The aircraft plunged about 17,000 feet in about a minute, but no one on the ground was injured.

Brazil’s aviation accident investigation center claimed in a statement that it “guarantees” no news outlet had access to the voice recorder’s audio, transcript or data, though it did not comment directly on TV Globo’s report.

Footage captured the moment the plane precariously spun out of control as it plunged into a cluster of trees.

The pilots didn’t relay any emergency or poor weather conditions before they lost contact with workers on the ground.

The audio will unlikely pinpoint the cause of the crash, Globo reported, citing those involved in the investigation.
