If you bothered to read the thread properly, THERE is a first hand account as relayed by position & hold. It's a report as she saw it, not as is all too usual on here by posters who throw up every conceivable (and at times some pretty bizarre ideas) as to what really occurred.
People just seem more anxious about getting their comment into a thread instead of ensuring it is contributing to the thread and not detracting.
Whilst there appeared to be a slow start, once the evacuation commenced, it was all handled very professionally, with credit due to all aboard and the ground crew. What appears to be in need of improvement is for better communication, which no doubt will be addressed by the appropriate authorities. It should also address the continued mindless reaction of some pax to bring their luggage when ordered to evacuate, as happened previously in the Hudson ditching.
Let's just be glad that all got off safely.
