Missing Link - I liked the statement on your profile "Loose nut behind the wheel". We had a similar saying when I taught young impressionable folks to fly helicopters. It referred to the student and was "loose nut between the cyclic and collective". If you are not familiar with helicopters, those are the names of the 2 main flight controls. Bottom line, your statement is well said and very universal.

Out to lunch
