Can't take credit for this shot -- Sándor took it with his 70-200mm lens. but I was the driver as our rental car got buzzed by spotter planes and fire-fighting tanker jets in southwestern Utah last weekend. The fire-retardant seen here is being dropped on a fire that came within 10 feet of a new housing development.
The exposure time on this picture was 1/1600th of a second, enough to freeze the tanker's propellers in mid-rotation.
