...more info; what is a plug door, how is it used, what the ''bolts'' are for.

...why did the Pilot's door fly open? (a second question which should be answered)

Because when the cabin pressure suddenly dropped when this 'PLUG' fell off ....... it released the cabin pressure! The door to the flight deck was locked shut (as the regulations require) so the flight deck pressure being higher than the cabin pressure blew the door open. I believe that door opens outward to make a rather flimsy door that much more resistant to forced entry.

Simple .....no mystery ............. if you think about it

Even if they wish to put a row of seats where the plug is, why not leave the door alone and put the seats there anyway? Why weaken the structure of the plane?

Boeing must have made a few pounds extra profit on that one as the door must cost more than the plug. So the airlines get a few extra seats, Boeing gain a door they can use elsewhere and fuck the public. They should both be facing the consequences of their decisions. I don't think that will happen though, corporations never do.

...there is a pressure relief valve on the door, or so their should be, so that the door remains closed.

RW the fact that the door opened is beyond doubt. If indeed there was a pressure relief valve and it was fitted by Boeing, than it is reasonable to assume that either it was not fitted correctly or it was just faulty.

I doubt it is a 'pressure relief' valve ? I would say it was more an equalising vent as its normal use would be to equalise the pressure changes between flight deck and main cabin during flight, which are very small. It was NEVER intended to cope with explosive decompression. Hence the door blew when the cabin pressure dropped in a matter of seconds.

This will most certainly give ideas to terrorists how to get into the cockpit with the cockpit door wide open.

Just for them to find a way to make the cabin pressure drop suddenly!

It will be easy on the B-737 Max with a plug for a door!

I wonder how windows are fitter. I bet a good wack with a small hammer will do the trick. In the meantime it goes from bad to worse.

A domestic All Nippon Airways (ANA) flight in Japan has returned to its departure airport after a crack was reported on the cockpit window during the flight.
