One other thing that works against Soaring as an Olympic event is the fact that worldwide, there are few participants compared to any of the other examples named. Millions of sailors, equestrians, and yes, climbers and surfers make up a visible market. Soaring, with at most a few hundred thousand pilots is too small and the cost to do a "first class" Grand Prix broadcast (New Zealand, Andes) would be prohibitive considering only a few countries could afford to send a team. Televising a soaring contest of any kind is massively more complex than showing sailing or any other sport, simply because of the distances, speeds and the third dimension of altitude.
