Mystery Deepens: Brazilian Plane Crash Investigation

Authorities have retrieved the full transcript of the black box from last week's Brazilian plane crash that killed 62 people. The recording revealed a steep loss of altitude before the crash but did not clarify the cause. Potential icing on the plane's wing is being considered.

Authorities investigating the Brazilian plane crash that killed all 62 on board last week now have the full transcript from the cockpit voice recorder. Local TV station Globo reported that its contents did not immediately explain the cause of the accident.

The transcript indicates the pilot and copilot noticed a steep loss of altitude about one minute before the crash, according to unnamed sources. However, the audio or transcript has not been publicly released. Brazil's aviation accident investigation center, Cenipa, confirmed that no publication had access to the voice recorder's audio, transcript, or data.

The ATR-72 turboprop plane from Voepass was en route from Cascavel to Sao Paulo when it crashed in Vinhedo, killing all on board. No emergency or adverse weather reports were made prior to the crash. Experts and authorities are considering the possibility of an icing issue on the plane's wing as a contributing factor.
