Is it possible that they inadvertently closed the valve completely, overwhelming the two pressure relief valves causing the door to blow out like it did? Seems like these plug doors would be the next weakest thing to give way.

Would have taken enough cycles. Not armchair QBing how the crew handled the manual pressurising system but who knows.

Article also said that the decompression was strong enough to “blow the cockpit door open”…. which seems odd for a number of reasons. Can anyone confirm that happening?

National Transportation Safety Board (NTSB) chair Jennifer Homendy said on Sunday no data was available on the cockpit voice recorder because it was not retrieved within two hours - when recording restarts, erasing previous data.

Did someone forget that part of the NTSB checklist or was the flight from and back to PDX so long that the CVR ended up hitting the 2 hour mark and overwriting itself?
