It is undeserved to describe private pilots as opposing the enlargement of the LAX Terminal Control Areas, just because we are "unhappy about losing uncontrolled airspace." Your article talks about how the FAA's regulations are largely reactionary, not preventive. The result is that when an accident such as Cerritos happens, the FAA imposes more restrictions. What is needed is for the FAA to redesign the airspace so that it can safely accommodate all of the traffic in the L.A. Basin.
That is why I am unhappy about losing airspace. I am being denied access to airspace and sometimes a margin of safety because the FAA is reacting by blindly grabbing more airspace instead of rethinking and redesigning airline and general aviation access to the basin's airports.
