Oh man, I was out flying this afternoon (training aerobatics, 2000' hard deck, 2500' lower limit and BKN033 - good practice) and missed this slugfest. Three pages in, what, four-five hours? Fortunately it's all recorded for posterity.
Anyway,
Isn't the whole purpose of the 250kt speed limit to allow see and avoid some chance of working?
Don't know if that's exactly true, but I do remember seeing somewhere that airline cockpit windows have to withstand a bird strike (of a certain size/weight bird) up to 250 knots.
