Hell of a way to go.

 

More jumping to conclusions, we are not allowing that here. They could have been missionaries and that was on an earlier flight. Oh and Racist!!!!

 

It is not hard you just have to know how to lower the jacks.

 

You can probably add misogynistic to the list as well

 

Who is this Mitchell Casado dude on CNN? The gruff goateed, t-shirt wearing, 777 "pilot trainer" at some Canadian airline enthusiast's FBS thrill ride company.

Nope. I doubt MH allows cockpit jumpseaters, and no word of anyone in the cabin.

 

What about the two S. African ladies?

 

Q - Is it possible to plunge a plane like the 777 into the ocean without leaving any debris behind? Low speed/low altitude then 45º plunge?

 

Back to our regularly scheduled programming...

So if our hypothetical bad guy used altitude excursions to disable everyone in the back, why did the airplane fly on for hours and then vanish? What was the point of it all then? Maybe just an unbalanced individual like what was alleged in the case of Capt Button? But if there was a rational motive (terror, theft of cargo) then why didn't it happen?

A flight 91 scenario is possible but it seems it would have happened much sooner, if at all.

How about this...someone in the cockpit could survive in the high flight levels ONLY if he used the appropriate setting on the oxygen mask, and used it properly. But any little mistake in that and the perpetrator would find himself disabled before he knew what hit him. Also...if he flew above the 30's the mask would NOT protect him from the bends unless he had pre-breathed pure O2 long enough to purge all the N2 from his body. He wouldn't have had time to to do that, even if he knew he needed to. Perhaps the perpetrator inadvertently took himself out along with the pax during that altitude excursion, and then the plane flew on AP following whatever route the perp had programmed until it ran out of gas.

 

You would have to land the plane like Sully and then let it sink intact.

Any sort of impact would break up the plane and release all sorts of debris, much of which would float.

But that's mostly irrelevant...it's a very, very big ocean and wind and waves would quickly disperse any debris such that you would not be able to spot a defined debris field.
