Bringing this over:
taking control of all the people on that plane would take a large number of people.. not just some cockpit takeover. They would have to somehow subdue all the passengers and take all their electronic devices. :twocents: just my thoughts here
There was a discussion earlier, about a potential way to instantly subdue ALL of the passengers. When the plane elevated to 45000 feet, the passengers would need their air masks. Those masks could have been tampered with, which would potentially disable and then kill all of the passengers.
This is REALLY chilling and a bit creepy... but here is the explanation for this.
The pilot (or whoever is flying the plane) has control over the oxygen in the cabin.
They can turn it off... basically causing a decompression. They could do it before anyone had time to react. :scared:
They could have flown up to 45,000 feet... turned off the oxygen and killed everyone within minutes.
Especially if they flew a bit erratically and made it difficult to put on masks. They'd lose consciousness fast.
The masks that drop down are only meant to allow time to descend (10-15 minutes.)
They could have used the *advertiser censored* pit oxygen (90 minutes total in the *advertiser censored* pit) while they did this.
Then dropped back down, turned the oxygenation back on and not had anyone to fight them. :twocents:
The cabin pressure is generally done automatically but there is an option to do it manually.
All a pilot has to do is not turn that on, or turn it off and put their own oxygen mask on... and everyone else will die. :scared:
(Also flying to 45,000 feet may have caused the engines to stop.
They'd have to dive to 25,000 or below to start them again.
That's another possible explanation for the plane dropping that low that fast.)
In the Helios Flight 522 this is essentially what happened except it wasn't intentional so the pilots died too.
The cabin pressure was set to manual from maintenance the day before and the pilots did not realize it.
When they started climbing people couldn't breathe and the oxygen masks dropped.
The pilots did not know the oxygen masks had dropped and kept climbing.
Then they misunderstood all the alarms that were going off... and lost consciousness before they figured it out.
There was also 3 hours of extra oxygen (separate from passengers and *advertiser censored* pit) on the Helios Flight.
That flight flew on auto pilot until it ran out of gas and crashed.
(There is a documentary on youtube about it if anyone wants to watch it.)
If the cabin was depressurized at that altitude, would it kill people instantly?
If not, it takes at least 5 minutes to die from oxygen deprivation, probably more. And if some passengers were able to use the masks, add that time on. Were they at such an altitude long enough?
They would still die at lower altitudes, they didn't have to stay at 45,000 feet the whole time.
Honestly it would make sense to disable the oxygen in the cabin and put your own oxygen masks on.
Then climb then descend quickly to make it hard for them to put on their masks.
In Helios 522 it was 18,000 feet when the cabin masks dropped and the flight leveled off (auto pilot) at 34,000.
The pilots were unconscious without their oxygen on before they even hit 34,000 feet. :twocents:
