On my arrival in Bozeman last week to cover the explosion that destroyed downtown buildings, I found the area already taped off with no access to make a picture of the scene. As I was shooting pictures of fire fighters around the scene I was also making phone calls to get an airplane for an aerial photo. Aerial views often are the best angle for coverage of big breaking news events when access becomes a problem. I have used aerials at floods, fires, train wrecks and even a couple of semi tanker accidents that closed the highway for many miles.
I always try to use Cessna and Piper Cub type aircraft as the windows can be opened. Plexiglas windows can distort the picture. A shutter speed above 1\250th of a second works the best to keep camera movement from turbulence and engine vibration to a minimum.
