Because it’s first and foremost a security door, maybe certain technical details of its design weren’t made common knowledge. On purpose?

This tidbit was news to me. Operationally, it’s hard to see how it makes any difference.(It’s all out there now though.)

In a rapid depressurization, everyone in the back is donning masks and getting cellphones out (not necessarily in that order).

The average passenger isn’t going to care, or notice, that the cockpit door is open.

(Could just be garden variety misreporting. Including the NTSB brief. It’ll all get sorted out in a few months)

The NTSB checklist or whatever you're airline calls it ensures that you pull the CVR and FDR breakers after an NTSB reportable incident or accident (obviously on the ground with parking brake on of course). This ensures that the CVR and DFDR drives don't overwrite themselves like what the NTSB claimed happened to this crew.

I wonder if Sully ran that checklist on his way out of the cockpit. According to the movie he did grab the logbook.

Nothing secret about cockpit doors. You can buy one on eBay.

If I buy two, do I get a discount? 😂

If they're Boeing cockpit doors then yeah, you do.

just don’t forget to go to Home Depot and get bolts, they don’t come with the door

That's because they were originally certified on the B-17.

Are you sure? This makes it sound like the whole door.

I'm guessing the panels are for cockpit depressurization, and the entire door opens for cabin depressurization.
