The Hudson was 1 to 50 - 3 FAs and 150 pax - they got them all out.
True but why did L1 open without correct slideraft deployment at first then magically corrected later?
If both forward sliderafts had been correctly deployed then all pax would have been in the rafts and not standing on the wing with at least one falling into an icy Hudson river...
As Airtags said these evac simulations done especially when testing new aircraft should be done with crew who have done a sector previously and as with tech crew sim sessions some problems thrown at them such as simulated fire outside an exit and some slides failing after opening....
