Maybe it's time the authorities re-thought the safety implications and adjusted the requirements to modern aviation....cleared area requirements date back probably to the '50s.... a 744 fully laden has iinertia way beyond anything contemplated 50 years ago....a fully loaded 380 will take us into another dimension (metaphorically speaking for any pedants out there)...one day not too far into the future cargo 380's will be operating regularly out of the same airports....Airports need to be within reasonable distance of the city's they serve...land within that same distance is always expensive as it's considered commuter friendly....ultimately and inevitably safety factors will always be compromised by the financial bottom line....it's an aviation fact of life...
