Never trade seats with Shatner.

True... But would not be hanging out the window...
Ah, the resident FR male hater chimes in.
Still smarting over whatever some male did years ago....
They were right, they said that a bullet hole in a plane would not cause explosive decompression. A hole the size of a window could.
Well,, correct, kinda.
True the pressurized atmosphere in the cabin would vent quickly outside until the venturi effect of the wind rushing by the ruptured cabin at 450 mph would continue to lower the pressure inside to well below that of the outside- think of how your lawn mower carburetor works, suction from the engine through a tube in the carb draws fuel out and into the intake- by lowering pressure.
Similar, but not quite the same
Now, as to a bullet hole in the cabin wall, too small to either depressurize rapidly nor allow the venture effect to draw out the atmosphere rapidly. The cabin air pumps probably are busy overcoming small leaks all day long anyway.
We don’t know yet how accurate that information is.

The turbine wheel is far fwd of the window impacted because you are in flight there is no way to know where the blades will fly however that has zero to do with the incident. The front cowling came loose from the front of the engine. Check in the pictures of the engine the pointy center portion of the intake it is a dummy cover to streamline the engine. The turbine wheel is about 4 feet aft of where the front cowling is located. What probably broke the cabin window was a section of the air intake cowling this is the second instance of a fwd cowling of a CFM56 on a 737 coming loose in flight. If I was acting as flight crew duiring pref light I would check the hell out of the fwd cowling latching mechanism 2 - 3 times....BTW thats the 2nd officers job on a 737 not the pilots....it was a man the woman has other duties as Pilot...
You are wrong its called a “RAPID D OR DECOMPRESSION” all military flight crews go thru the altitude chamber an see how a rapid d occurs by the operators of the chamber kicking pressure out of the chamber instant snow storm. Remember at sea level its 15 psi aircraft are pressurized internally to enable movement in flight hence if the fuselage or window is ruptured everything goes out a hole in the fuselage. Notice in the movie AIRPORT when on the ground and they look in the lav were the bomb exploded all the sides of the hole were bent outward because of the air pressure...
“WTH does gender have to do with it?”
They want us to be aware that she knew exactly where she was and didn’t have to ask for directions.
B29 bombers were pressurized and shot all to hell during WWII. No one got sucked out unless a giant chuck of the plane was removed by AAA and even then it rarely happened because they were strapped in most of the time.
No, I am not wrong. There is no SUCK. Read your own words.”everything goes out the hole” ... due to internal pressure BLOWING air out the hole until the internal atmosphere reaches the same ‘atmosphere’ as outside the plane, then the air STOPS blowing out. That is legit physics.
I am not going to argue further with you, because while you may have gone through altitude chamber training, you misunderstand the physics of air pressure. The mechanical mechanism of that chamber reduces air pressure below the pre-existing 1 atmosphere level, but trust me, it is NOT the same as the pressurized fuselage PUSHING out a broken window.
“They were wrong. It can happen.”
I didn’t know. I thought it was Hollywood overkill.
Still disagree with you. The venturi effect is LONG debated - is “lift” on a wing a push or a pull? As a student of physics long ago, [LONG ago!] with an understanding of gas “pressure” at the molecular level ... it’s a push, not a pull. Sure the venturi effect reduces the pressure on the top of a wing, but the lift cannot exceed the force of the push per square foot per second below.
PERHAPS the wind rushing by that hole would reduce cabin pressure slightly, but it would still stabilize, and NOT continue to reduce pressure by causing more air to continually push out the hole. You cannot evacuate a cylinder by blowing air at any speed across the opening.
If you believe the venturi effect would evacuate the fuselage, we need to disagree.

Horrifying.

Embrace the suck. ;-)
Which is why a Submarine will “Implode” when it goes too deep.
Pressure always wins...
Thanks for the laugh!!
News pic showed smashed window in passenger’s head range. Likely shrapnel. Poor thing.
News just said “someone went out”.
