There is something really cool about watching a hunk of metal defy Mother Nature and fly through the air at the most dangerous point of the flight, low, right over your head, and then land on a hard piece of asphalt, all while contributing to your long term hearing loss.
This photography is fun and fast. The busier the airport, the better your chance of getting a good shot. Just pick a location with a view of the approach end of the runway (important detail) where you want to get the ideal angle of the airplane. Hey, you may even get a few good shots of an airliner taking off too.
Here are 15 examples to help show you where you may find a good angle to photograph airliners landing at your favorite airport. Another great site that is a host to a lot of great photographs of airplanes is airliners.net.
