Plane crash: what physics reveals about the 76-second descent
51 sec Machine translated Crime & incidents
Nine people, 76 seconds of falling. What did they feel inside?
The black box was found, but its recording isn't out yet.
But physics can already answer part of that.
First, the nose dips and the body feels weightless, like going down a roller coaster.
If it descends too fast, anything that's loose rises.
In 30 seconds, the jet had already exceeded its speed limit.
By the end, it was falling at over 900 kilometers per hour, straight down.
Almost five times faster than a skydiver.
A person falling is held back by the air, but a sleek, heavy jet punches through it.
And it didn't fall straight down, it descended in a spiral, turning halfway around.
In the turn, the force presses the body against the seat.
And if the pilot pulls the nose up, it presses harder.
If that force builds quickly, blood drains from the head, vision closes in, and the person may black out.
If that happened, no one knows yet. Part of the answer may be on the recorder.
With what these… went through

Nove pessoas, 76 segundos de queda. O que elas sentiram lá dentro?
A caixa preta foi achada, mas o que ela gravou ainda não saiu.
Só que a física já responde uma parte. Primeiro, o nariz desce e o corpo fica leve, como na descida da montanha-russa.
Se desce rápido demais, o que está solto sobe.
Em 30 segundos, o jato já tinha passado do limite de velocidade.
No fim, caía a mais de 900 por hora, só na vertical.
Quase cinco vezes um paraquedista. Uma pessoa caindo, o ar segura, o jato liso e pesado fura o ar.
E ele não caiu reto, desceu em espiral, fazendo meia volta.
Na curva, a força aperta o corpo contra o assento.
E se o piloto puxa o nariz, aperta mais.
Se essa força cresce rápido, o sangue sai da cabeça, a visão fecha e a pessoa pode apagar.
Se isso aconteceu, ninguém sabe ainda. Parte da resposta pode estar no gravador.
Com o que passaram essas...
