I don't know but thankfully my ignorance of the subject must be what allowed me to have survived all those trips.Haha, of course CAT...a piece of paper definately makes flying boats on the side of an airplane safer! How could we not see this before?
Same thing with that video they cobbled up called " When in doubt "
It is beyond my ability to properly express the feelings of fear and relief I felt the first time I watched that video, up to that point in time I had no idea that flying with frost, ice, snow or any other contaminating stuff on the wings and the rest of the airplane would make any difference in how the thing flew how I had survived up to that time in my career is beyond me.
