ALBUQUERQUE, N.M. — Many were horrified on Tuesday upon learning an Albuquerque woman was killed after being partially pulled out of a plane when a nearby window was smashed by debris from an exploding engine.
“Two words: extremely rare,” said Alan Diehl, a former air safety investigator with the National Transportation Safety Board, Federal Aviation Administration and U.S. Air Force, of incidents involving passengers being pulled from planes in flight.
But on Nov. 3, 1973, a similar scenario unfolded on a flight over southwest New Mexico heading from Houston to Las Vegas, Nev.
Then, a Texas man died after he was pulled entirely from the plane when an engine on a National Airlines DC-10 flight blew up. G.F. Gardner, 47, of Beaumont, Texas, was pulled from the plane at 40,000 feet over an area near Magdalena.
His skeletal remains were found two years later during construction of the Very Large Array radio telescope near Socorro.
“That engine literally fell apart,” passenger David Drucker told the Journal in a Nov. 5, 1973, article.
The plane made an emergency landing at the Albuquerque airport, and 24 of the 127 surviving passengers and crew members were treated for smoke inhalation, ear problems and minor abrasions, according to the 1975 accident report by the National Transportation Safety Board.

United had a DC10 back in the late 80’s that the cargo door ripped off and tore a big hole in the right side, which several window seats were blown out over the ocean, the flight returned to Honolulu.
By golly, it’s been an almost daily event and I missed it!
Explosive Decompression - Loss of Cargo Door in Flight, United Airlines Flight 811 Boeing 747-122, N4713U

Correction it was a 747 not a DC 10...
N4713U after the cargo door tore off in flight and caused an explosive decompression. Nine people were ejected through the hole.
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.
Yes. They didn't know what was going on until they were able to recover a Comet that had crashed and found the stress fractures radiating from the corners of the windows. Prior to that recovery they had lost a few Comets but were never able to find them. I think they were all lost over water but I might be wrong.
So if the ventilation system can keep the plane pressurized with only a window blown why did the O2 masks fall and some of the passengers suffer from altitude sickness?
No, the ventilation/pressurization system would not be able to keep the plane pressurized, but would still be producing positive pressure that would instead be going out the window hole. The pressurization system would be producing less pressure due to the engine failure, as bleed air from the engines is used to create the positive pressure. Some of that would be offset by the instant closing of the outflow valve that allows excess pressurization to escape from the fuselage.
Actually, the person was blown out.
The pressure differential is from high pressure inside to very low pressure outside.

Well I truly would be thrilled if all/most of the Q stuff turns out to be real.
