How come skydivers don't get sucked out by the change in cabin pressure when the airplane door opens?

    Airplanes that can be pressurized have controls that the pilot can activate to gradually depressurize the plane before a door is opened. Military paratroopers do sometimes jump out at high altitudes from planes like a C-130 that are pressurized until a few minutes before the jump.

    a million. Air rigidity decreases with top - so if the airplane remained at sea-point rigidity interior, and not a lot rigidity exterior - then this could positioned an spectacular rigidity on the airplane epidermis, at last optimal to failure and explosion (see the background of the Comet, or the BAC1-11 that had the incorrect screws put in the windscreen and it blew out using inner rigidity). 2. the interior rigidity won't be able to be equalised to the exterior rigidity at severe altitude, as there purely isnt sufficient Oxygen to stay to tell the tale (see what got here approximately to the Helios B737 some years in the past). The cabin rigidity is stored at around 8,000ft - mushy for the team and passengers - not too a lot rigidity on the airframe.

    Oh; the turbulence around the open door does tug a bit. And the occasional sky diver DOES exit the aircraft earlier than he/she planned to. But the turbulence is not really all that bad and it's not like these aircraft are pressurized either.

    It should also be noted that the jump master does not just let the door open suddenly either. And he also gives ample warning before doing so. There ARE certain safety protocols that they DO follow.

    because the airplanes used for skydiving fly low enough where there is no need to pressurize the cabin.

    Everyone is pretty much right on, but there's another little detail: most planes used for skydiving have one door completely removed. They don't have to open them in flight, because they are never closed!

    The aircraft skydivers jump from are not pressurised, and skydivers jump from low altitudes so there is no change in pressure.

    Skydiving planes aren't pressurized like airliners are.

    So, there is very little pressure difference between inside and outside.

    Because the cabin is not pressurizied on those planes and usually they are not jumping out at altitudes above 10-15,000 ft. Usually.

    The plane is not pressurized, If it was you would not be able to open the door.

    This happens because the plane is not pressurized
