many, but depends on photographer's choice of file upload (newer event = more likely to work) and your device's capabilities. You may experience slow playback, distorted images or unexpected browser quitting if there is only limited memory/GPU power available.
This has been a busy and exciting year for me. The panorama is actually one of the few that I've taken this year as I've been spending most of my time doing what you see me doing here: flying. The image may not be my best panorama in a long time, but it does a very good job representing 2009.
This is a Traffic Watch flight. We fly over the highways and freeways of the SF Bay Area. The pilot handles the plane, the airspace, the weather. The reporter sits in the left seat, observes the traffic, and reports it to local radio stations. Some days it's more work than others - usually due to the weather. But many days we spend 2-3 hours at a time enjoying the view from above one of the most beautiful places on earth.
Special thanks to Derek for helping out with this panorama and for being an all around fun guy to work with.
