A top aviation expert has revealed the most likely causes behind what caused a Brazil passenger jet to ‘death spiral’ in a horror crash today. on Friday showed a Voepass airlines plane falling from the sky as it plummeted behind a cluster of trees near houses, followed by a large plume of black smoke that killed all 61 people onboard.

Captain Ross Aimer, who has over 40 years of experience flying passenger jets in the US, told DailyMail.com that the tragic plane could have experienced engine failure, flight control malfunction, or if a critical part of the aircraft – like a wing part – fell off.

And once you enter the death spiral, ‘it’s very hard to get out of it,’ he said.

This happens when planes move too slowly. The three reasons this happens are either a technical fault, extreme turbulence, pilot error or something hitting the wing, like a bird.

The Brazilian Air Force reported that it has sent a team of investigators to the site.

While speaking at an event in Southern Brazil Friday afternoon, Brazilian President Luiz Inácio Lula da Silva called for a moment of silence for those lost in the crash.
