Cough, I can see how that could occur. I presume you are talking about a type other than a 737 though? (as there is no such thing as a flap 1 departure)
Also, I think the original post was about raising the flaps after take-off as supposed to the gear, rather than inadvertantly raising all the flap at Aa.
I still think this sounds completely unlikely on a 737, anyone else?
