This, in my opinion, was an accident waiting to happen. Over reliance on automation causing complacency, lack of training,
In some cases that is proved to be true: however, these were not inexpereinced pilots. They had flown other less automated types.

Positive rate - gear up.
If you do and say this, you will live.
No doubt this is how they had been trained on other types, as it is pretty standard, especially with less automated types. The physics haven't changed.
I often wonder why pilots bin their experience from previous days when they are told to 'let the automatics do it for you, stop cross checking': 'follow the FD' etc.etc.
