Investigators are piecing together the final moments of those onboard the Voepass Linhas Aéreas Flight 2283 after recordings from the black box were retrieved from the wreckage.
It captured a series of chilling sounds and terrified screams as the twin-engine turboprop tumbled out of the sky and crashed in the town of Vinhedo in São Paulo, Brazil, last Friday (9 August).
The 58 passengers and four crew members who were on the aircraft - which was bound for Guarulhos International Airport - were all tragically killed, with officials saying 60 of the victims have been identified so far.

Terrifying footage shared on social media showed how the the aircraft spiralling out of control, before plunging down into a cluster of trees - but by a miracle, nobody on the ground was hurt.
One traveller onboard the plane, 23-year-old Rosana Santos Xavier, had harrowingly sent her family a selfie before telling them she was 'afraid of this flight'.
The cause of the crash is still yet to be determined, but a preliminary report on the incident is expected in around 30 days.

For now, the contents of the black box which was retrieved from the wreckage of the Voepass jet is the only thing which can provide an indication of what exactly went wrong onboard flight 2283 last week.
The transcript of the final conversation in the cockpit is somewhat imperfect due to the propellers of the ATR 72-500 being located close to it on top of the fuselage, which therefore creates excessive noise and makes it harder to understand.
However, according to the Brazilian television network Globo, the noises it did pick up suggest the two pilots suddenly realised that the plane was experiencing a sharp drop in altitude approximately one minute before the devastating crash.
Co-pilot Humberto de Campos Alencar e Silva is said to have been heard asking 'what was happening' before frantically requesting an increase in power, which he reportedly hoped would stabilise the plane and stop it from falling out of the sky.

The distressing recording then came to an end with a loud bang after the screams of the 62 people onboard were heard, according to reports.
But throughout the recording, there were no distinctive warning noises - such as ones which would alert the crew to an engine failure, fire or electrical malfunction - picked up in the audio from the black box, the outlet further states.
Voepass said in a statement earlier this week: "The aircraft took off from Cascavel-PR bound for Guarulhos Airport, with 58 passengers and four crew members on board. VOEPASS has taken all measures to support those involved.
