The small and very active community of aircraft photographers and videographers is putting up some superb material on the usual outlets. Close to home, many shoot from El Segundo’s Clutter Park where they can get nice views of LAX’s south runway operations although with some interference from low buildings.
Then, there is Youtube’s SpeedbirdHD. He says little about himself other than that he is an aviation enthusiast in Los Angeles. There must be more to it than that. He has unique access to LAX operations, almost assuredly through a job on the premises. His videos of the heavy metal flying in and out are in a league of their own. Speedbird and his HD camera get tarmac footage of regional jets, superjumbos, and even the occasional miltary lifter from every runway. His edits usually include relevant air-traffic control conversations in the background. Top class stuff.
Here’s his channel. His 2012 highlight reel is a good place to start.
