Guys and girls,
Thank you all for the inputs and thoughts.
But,
The RAT heating working on the ground should NOT have anything (alone) to do with the cause of the accident.
OK, they returned because it was heating on the ground.
They MEL-ed it, maybe the wrong way, because the heater was not inoperative! It was working just fine!
Question should be; did maintenance do the correct procedure?
All of this has nothing to do with a flapless (slats?) take-of! (besides the TOWS) but i donīt think you can blame MD/BOEING/SPANAIR-procedures/MAINTENANCE for pilots trying to get airborne not configured as briefed.
I know, a lot of things will come together and will have some kind of a influence of the whole accident.
For me the question remains: Why did they try to get airborne without flaps without having the proper speeds for that? Rush? Overconfident?
