Why does a hole in a flying airplane cause things to get sucked out into the sky?
In: 0
they’re not sucked out, they’re pushed out…. Airplane cabins are pressurized to about 8000 feet vs planes flying at 35000 feet where the air pressure is lower. Air rushes out of the plane (wind) trying to equalize pressure. And takes anything along with it.
The secondary effect of the air outside the plane moving much faster (relative) to the air in the cabin can create air currents in the cabin. Sometimes if you open the windows in a moving car, papers/etc inside can get blown out.
