I have yet to see an aircraft manual, a training manual, or any other aviation printed material that condones taking off with a contaminated wing, or says that it's ok to take off with just a bit of ice. His argument that the aircraft was defective because the manuals didn't say the aircraft was suceptible to icing is a crock. With so many lawsuits these days I imagine that the legal profession is one of the most robust and fastest growing sectors of our economy. YUCK
