What puzzles me is why we still don't know at exactly what altitude they overflew Haarlem with all these live-flight trackers around nowadays. The MSA following a departure off 19L with an immediate right turn is 1700 feet. I assume the crew would at least try to reach that altitude. Overflying a city at 1700ft with one engine at MCT may be quite unsettling for people on the ground, especially with one engine spitting out feathers and engine parts.
From the route flown it looks like the crew didn't get/take the time to read any checklists..
