Pretty sure the QRH drives you to attempt and control the cabin pressure manually, so it shouldn't be a surprise if they did in fact make that effort.

Man the Monday morning quarterbacking is great. Imagine you're climbing out of PDX on a normal ass day, through 10 and you start chatting about how Biden is destroying America, and at 15,000' you hear a loud ass horn and it takes you 10 seconds to realize you're in a rapid D situation. You follow your memory items, call for QRC, and then have to worry that a bunch of mouth breather on APC question your decision making not realizing in 45 seconds that an ENTIRE PANEL blew off your airplane. Y'all at Delta and Frontier get that on your LOFTs as a common occurance? An entire piece of your airplane blows clean off your airplane because of defective bolts?

I didn’t convey what I was attempting to say well, that’s on me, In the NTSB brief it sounded like the controller switch was still in auto as in only 1 channel of the auto made failed the 2nd channel was operating as it should therefore keeping the switch in auto. They are saying as of now they do not think this was a cause. NTSB says it was MAN but was in auto

Around 8:50 in you can listen sounds like it was in auto still functioning as it should

WSJ reporting:

"What the flight crew didn’t know at the time, federal investigators said Monday, was that it was supposed to happen that way. Boeing had designed the cockpit door to open during a rapid decompression incident, they said. The company just hadn’t said so in the manual."

Boeing says the cockpit door is supposed to blow open during a rapid D.

Amazing. Have you guys ever heard this?

The entire door doesn't open. The "doggy door" on the bottom and the top open. It's in the Boeing system handbook under general. Those panels aren't there for dogs...

Same on Airbus.

I actually was responding to magiccarpet. Your post jives with my understanding of the situation.

Looks like the blowout panels are only for a loss forward of the cockpit bulkhead. For an aft rapid decompression, apparently the door is designed to open.

I think they should have told some of us

At least let the people know who stand in the direction of travel of that door... Sounds like it hit the forward lav door so violently that it could have hurt someone.

They were at 16,000 feet. Seat belt sign would have been on and no one but maybe FAs would be walking in cabin. If it happened at cruise in mid 30’s probably would have been a hull loss anyhow.
