Below is a very interesting audio narrative provided by Gary Mortimer in South Africa interviewing the actual creator of these custom camera platforms for these types of shows.

Hes a seriously cool dude and the modelling toys he had in the shed were amazing.
The self levelling camara that they strapped to an elephant in India to keep the from Elephant shots level were cool.
One of the shots in Trek was taken with a normal Sony point and shoot camera, a ws 30 I think on the front of a tiny electric heli. I'm not telling you which one!!
Cheers
