I'm living about 7 miles east of the start of runway 27 of Schiphol Airport, or AMS/EHAM. Planes pass just to the north of me on their approach at about 2,000 ft.
At some point, I started taking pictures of passing planes from my garden, and pretty soon thereafter I put these pictures online. To keep the bandwidth and disk space requirements manageable, I resized the original pictures to 900x600 pixels. I do have (almost all of) the original pictures offline.
So, there you have it, the story behind the Backyardplanespotter page.
Things to find:
A note on the dates you might find on the plane pages, they're approximate. It's the time that the camera puts as meta-tags on the pictures, but cameras seem to have quite a clock drift, and I don't really synchronize the clock. It's accurate up to about 15 minutes.
