Capt Claret
Just how does a muppet on an aeroplane with no mid cabin underwing exits, open a door? Are you really suggesting the cabin crew just sat there and allowed that to happen?
It would seem you are blissfully unaware that precisely what I described has already occurred on this type before. Anyone familiar with the history of these aircraft will know it was possibly even this airframe!
it's entirely possible and reasonable, that the tech crew on hearing an explosive sound shut the engines down and ordered an evacuation.
Are you REALLY a professional pilot? If you think that's 'reasonable' you need to think again! That's absolutely NOT what we do round here!
If the explosive sound was just a compressor stall, and there's no visible damage to the cowling in the photo at the start of the thread, then why not evacuate from the starboard side. Finally, at a guess, the CC probably wouldn't all agree on which side the explosive sound came from and would therefore rely on what they could see.
It just gets worse!
You clearly operate on a different planet to me.
