I remember their RTO in GLA a couple of years back when passengers were horrified the the slides on the wing didn't deploy (!) and much was made about it at the time.
Look at video of the Southwest evacuation at LGA. Lots of people standing on a wing looking stunned and wondering where to go.
Yes in both incidents the issue may have been compounded by the lack of flap 40 selection, but I'd still expect them to be able to slide off the trailing edge wing root/flaps.
Modern day society though. It's always someone else's fault and you don't need to take responsibility for your actions.
I'm intrigued. Three minor incidents, a smallish fleet yet they've had three evacuations in the last two years. In this instance it seems a little half hearted. Two slides deployed, and at least one over wing opened.
Be interested to hear the report. Evacuations seem to happen all too often these days and they can be extremely dangerous.
