The issue that you are not seeing is that decompression happens much more quickly in small airplanes at high altitude rather than large planes at high altitude. ---There is plenty of reaction time in a large plane to get masks on and start down towards 15k.Ok B1.... you asked for it...
Read that again B1... and read it real slow.
---> What happened on this flight falls into the category of "extremely improbable".
So case closed on that.
Now in one of my follow up posts I spoke of the formulas required to calculate the time required for a pressurized container to reach ambient pressure if the walls of that container are somehow breached. As I pointed out, those are pretty complicated calculations, which require first order differential equations based on volumes, hole size, ambient temperature, viscosity, Boyles Law of expansion and ∆P. Those results must then be inserted into a second order differential equation and solved for ∆T.
That was of course off the top of my head, so for fun I included one that would need to be solved below, but these formulas are for engineers that require gnat's ass accuracy--- like in nuclear power-plants. And this is only one of the formula's required.

But B1 we don't need to do all that. I can spell it out for you in layman's terms that perhaps you'll understand, because I figured out a simple way to make my point here.
In an aerosol can, the pressure difference between the inside of the can and atmospheric pressure is 2X-8X

Lets use 5X --- it's in the middle.
Now... lets look at pressure differential inside our jet at 16,000 feet.

Lets use 4.0--- close enough. And amazingly close to our spray can.
Now look at this picture at the size of that opening

Now picture that fuselage as an aerosol can of hairspray. That hole is pretty big relative to the can right? Right.
Now go into your bathroom and grab a can of hairspray. Find the nearest screwdriver, and punch it thru the side of that can. See how fast it depressurizes.
Yeah. Pretty darn quick isn't it? And that's exactly what happened to Alaska Air.
It was such a violent decompression, one of the I-Phones they found... (it was being charged)... not only did it get sucked out... it took half the plug with it!

Now go get that can of hairspray and a screwdriver.
Make sure you where safety glasses.

Not seeing what?!! What you just wrote B1, that's friggin common sense.
If I have a 5 gallon bucket and a 1 gallon bucket and punch a hole in them, of course the smaller bucket is going to be empty first. Duh. This point you keep circling back too has ZERO to do with this debate. And even if it did, the rate of decompression in your small airplane, would depend on the size of the hole. If a door falls off a Gulfstream, yeah its going to lose pressurization in seconds. An airplane 4X as big, at the same alt and all else equal, would take ~4X as long with the same size hole. Maybe 8 seconds vs. 2? Whatever. I fail to see your point. A smaller airplane has a smaller volume of air. This is a revelation???
Try using the whole quote B1, hypoxia is a function of whatever cabin altitude is at the the time. It doesn't matter if it's a 747 or a G-IV.
When cabin pressure equals ambient pressure, you could be up there strapped to a weather balloon, it doesn't matter... the physiological effects are the exact same.

This type of decompression usually only occurs in small aircraft flying at very high altitudes.
What type of decompression?
PLEASE CLARIFY.
AGAIN---> We already covered this.
Do you need to read this a 3rd time? :
"NOT SHOWN TO BE EXTREMELY IMPROBABLE"
Rapid and Explosive
And put this in your pipe and smoke it B1...
Any (well maintained, or straight off the factory floor) aircraft that is certified with a pressurized cabin that enables it to legally fly above 15K, is no more likely to have a depressurization event than is a brand spanking new Boeing 7** or Airbus 3**.
That's like saying a 2 door Hyundai loss leader has a better chance of accidental airbag deployment than an F-350 does. No. It doesn't.
