Being pedantic here and the outcome was good but was it wise for the pax to stand on the wings? Remember the plane had just taken off so there was a whole lot of fuel in there and there must have been some structural damage to the tanks after the ditching. I guess it was the best of two evils really, stay with the chance of being fireballed or jump with the chance of hypothermia and/or drowning.
Also once the hull had been secured, would it not have been prudent to enter the cabin and strategically place some large inflation bags ensuring the hull wouldn't sink?
Just a few points I have mooted with myself and p.s. my previous post about landing closer to the embankment was just an example of black humour us pilots revel in.
