F3G,
Post trauma stress is indeed a horrible, long term experience but with the greatest respect and knowing we should wait for the reports etc etc, this flight appears to have been brought down by a flock of birds.
The employees of US Airways prevented a potential disaster rather than causing it so it is not surprising that people would be angry at such a response from a passenger.
Anyway, why not sue La Guardia airport instead or indeed, the Canadian govt?
After all, it was their geese.
