My translation from the Russian website "Butter Bread’s Laws." (z-bb.ru). Here's Brad's laws for this case (my apologies for the translation)
Butter Bread’s Lows of deicing aircraft
The first low of Butter Bread’s Lows of deicing aircraft.
The biggest problem of an icy airplane take off is that a lot more planes take off successfully than unsuccessfully.
The second low of Butter Bread’s Lows of deicing aircraft.
Takeoff on the icy jet is the same as Russian roulette, if you pressed the trigger and the shot is not heard, it only means that the next press the trigger PROBABILITY SHOT increases.
The third low of Butter Bread’s Lows of deicing aircraft.
If you decided to risk make sure that you risk only to themselves.
