Putting the viewer in the middle of the action is one of the great challenges of photography. To get that difficult shot I've always liked using remote cameras. They are a great way to get a point of view that would be difficult or dangerous or impossible otherwise. Some of my Photo Society colleagues (Tim Laman, Steve Winter, and Randy Olson to name 3 but there are more) have taken remotes to technical heights, using infrared beams and computers to trigger the cameras. I tend to take a much more low tech approach.
My MO is to clamp the camera into a hard to reach position and then fire it with either a radio remote or a simple intervalometer. In the photo above (and below) there is a manfrotto superclamp on the back rack of the motorcycle with my camera attached. An intervalometer is taped to the rack as well and it fires the camera every second as I ride along. This technique produces A LOT of bad pictures, but also an occasional good one.

If I don't want to sort through thousands of images and my hands are going to be free I'll use a radio to set the cameras off.

Here I have a camera mounted to each wing and different radios to fire them. Depending on how the pilot is banking I fire which ever camera is pointing at what I want a shot of. Important thing to note here, make certain your radios are taped down securely!
In a wet situation the camera goes in a waterproof housing and I'll use the radios again. I've found that even in a white water raft putting the radio in 3 zip lock bags and taping it to my life jacket works pretty well.

Once at Cataract Canyon on the Colorado River I was shooting this way when our raft flipped.

We all wound up swimming the rapid and I didn't get any photos out of the remote camera once the raft was upside down, but the triple zip locked radio remote came through just fine.
