The legalities around flying UAVs in the UK seem to be pretty complex but Tom M did a good job of finding out the important points for our project:
Its a bit of a shame we can't fly the UAV out of sight as using autopilot we could have done some nice long transects. That said I can understand why this is the law.
There are already quite a lot of people exploring the possibilities that drones offer the world of conservation. Thankfully this means we don't have to start from scratch.
