The Times made my day by posting a nice article on the "Expressway Visual", my favorite route into LaGuardia. It's a relatively-rare "visual approach", in which pilots find their way to the airport by using visual landmarks instead of GPS or other electronic methods. As the chart indicates, pilots approaching from the south fly over Prospect Park, pass the waypoint known as "DIALS", then turn right and follow the Long Island Expressway until they get to Flushing Meadows-Corona Park, at which point they make a sweeping left turn around -- or over -- Shea Stadium and line up almost exactly northwest to land on Runway 31. (Like all runways, it's named for the first one or two digits of its compass heading -- the opposite end is necessarily referred to as Runway 13.)
It's great fun to watch from the ground, too, especially for dorks like me who like to take pictures of airplanes. The planes' low altitude combined with their tightly banking turn makes for a dramatic flyby, and the planes go about three-quarters of the way around you as you watch. I like to go out to the eastern end of the World's Fair Promenade adjoining Flushing Bay and watch them wheel around me.
