What do you think of sharing Airspace with others?
These guys were wave riding on the updraft just above the cliff, so were unable to fly anywhere other than about 10 metres either side of the cliff top, and not able to change thier altitude significantly.

Sharing airspace with others? If your video is an example, it is a beautiful idea.

No problem at all. You can move  and change direction quicker than they can... heck, we've followed them and they LOVE the footage

No problem here either as I use to Hang Glide.  Just remember they have right of way. Fly safe.

In the U.S. we are required to stay well clear of, and make way for any aircraft with a person on it.
