[0:04](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=4) The black box was found, but its recording isn't out yet.

[0:07](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=7) But physics can already answer part of that.

[0:09](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=9) First, the nose dips and the body feels weightless, like going down a roller coaster.

[0:14](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=14) If it descends too fast, anything that's loose rises.

[0:16](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=16) In 30 seconds, the jet had already exceeded its speed limit.

[0:20](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=20) By the end, it was falling at over 900 kilometers per hour, straight down.

[0:24](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=24) Almost five times faster than a skydiver.

[0:25](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=25) A person falling is held back by the air, but a sleek, heavy jet punches through it.

[0:30](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=30) And it didn't fall straight down, it descended in a spiral, turning halfway around.

[0:33](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=33) In the turn, the force presses the body against the seat.

[0:36](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=36) And if the pilot pulls the nose up, it presses harder.

[0:39](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=39) If that force builds quickly, blood drains from the head, vision closes in, and the person may black out.

[0:44](https://www.translate.mom/transcript/8zYFVExwSOEj/en/plane-crash-what-physics-reveals-about-the-76-second-descent?t=44) If that happened, no one knows yet. Part of the answer may be on the recorder.
