What air gets sucked out as the cabin depressurizes must be replaced for air to continue to be sucked out. Those jets can’t pump air into the cabin that fast.
Once the cabin is depressurized it just wind and noise.
This has a nice little clip in it. Not that fast, only 150 mph, but you see little buffiting around the door. Doesn’t show the JM doing the door check. When the JM in the old days we hung way out the door with our hands on the insides and toes hanging out over the step.
I think commercial airframes leak enough that with the ventilation system and a hole that small, there would still be some suction from the outside at 400mph. Think carburetor main jet.
Now, at 150, with a hole big enough for a paratrooper, Bernoulli principal might actually have a small positive pressure, slightly pushing someone back away from the door. Think open house door on a windy day. All theory of course, but your example seems to play that out.
Smaller the hole, higher the airspeed, the more negative pressure. Bigger hole, slower speed at some point starts creating positive pressure.
