If there is one thing pilot's love, it is banter.

The A320 airspeed in the initial climb to 5000 feet will be about 200mph. Even if you see a flock of birds a mile away, which would be a miracle, you would be in the flock within 15 seconds or so, and a pilot's initial reaction would be to turn way to avoid birds being ingested into the engine rather than adjust the engines. Remember that these engines are certified to be able to take a bird strike from something like a pigeon with minimal damage.

As an ex Private Pilot, and having spent hours practising for engine failures after take-off, I find it extremely worrying that the commercial aviation world wasn't training Airbus pilots for double engine failures after take-off. While single engine failure after take-off is clearly an emergency that needs to be trained for, to not train for a double engine failure seems absurd. It is an extremely unlikely event, but given the likely outcome of a complete failure is so dangerous it is incredible to me that that this was not practiced for. Perhaps it is a hang-over from commercial aviation's earlier days when all Air Transport aircraft had four engines? With a four engine configuration, the chance of losing all four engines on take-off due to striking a single flock of birds would have been so low enough to reasonably ignore it, and system redundancy would have avoided a complete failure of thrust due to faults on the aircraft.

A great analysis, with great detail and insight. However, on your point about the APU/Ramair/Normal/Alt Laws, it seemed that because Sully started the APU, the aircraft was only able to follow the Normal Law, so Sully could not achieve the nose-high attitude he wanted. Consequently the landing speed and kinetic energy was greater than he wanted or was necessary to retain control of the aircraft. I am curious as to whether you think this was a good think that he could not do this, or do you think the aircraft would have been less damaged if he had been able to have full control over the aircraft?
