Remember that an evacuation must be a controlled event
...right....
"let loose the dogs of war..."
The crew have indicated their level of knowledge already, confusing a rotating beacon reflection with an engine fire.... and the passengers have been intent on the briefing to the extent they are disturbed that the over wing slides didn't deploy... yep... "controlled event" is not going to be the adjective to be used in this event, (nor a noun...).
Avoiding confusion in evacs is hard enough on a good day, and this was not one of the better performing crowd.
Good news is probably that the pax next flight will actually listen to the briefing or even read the safety cards. Wouldn't hold my breath for that though....
The purser called the other cabin crew to evacuate through the right hand forward and rear doors, but did not instruct to open the L2 door and overwing exits. However, door L2, both left hand overwing exits as well as both doors R1 and R2 and right hand overwing exits were opened.
All injured passengers had exited the aircraft through the overwing exists on both left and right hand side.
Wow! would have been interesting with a real fire from the LH engine...
