Skylion:
Look at the flaps. Correct landing settings?
You missed the bit on the end: "... for the circumstances". When we know the circumstances we'll know whether the flap position was reasonable.
Vanman:
If the reports that there were no PAs made from the flightdeck crew after the aircraft had come to a halt, and that the evacuation was Cabin Crew initiated, are true (which I hope prove to be false) then there was clearly some failing in the cockpit. Whilst I am loathed to criticise, clearly either a call for normal operations or a call to evacuate should have been made.
How do you know the flight crew didn't attempt to communicate with the cabin? Depending on the nature of the electrical failure and subseqent impact damage, it might not have worked. Or they were too busy with whatever shutdown procedures were left to do. Why shouldn't the senior cabin crew have authority to evacuate if they can't get through to the flight deck (who could have been unconscious/dead at that point), given that the aircraft was stationary, unlikely to move, and might yet catch fire. Best to get everyone out.
