Seems to me we are over regulating. What type of restrictions do they have in Europe? I have not heard or read of any accidents or injurius and most of the turbine development is done over there. What happed to "This is a free country" ,"And the pursuit of happiness"? Why the speed limit at 140, DF's have been exceeding this for years, some to 250 mph. The flying skills required of these are similar to the turbines, slow the throttle servo progressively and it is same. The airframes on the newer jets are mostly composite now to handle the extra weight and stress of turbine flying, are they not? Does it not just come down to personal responsibility on the part of the pilot? Just my .02.
