The horse evolved as a prey species...
What an interesting post. After all the idle speculation about horses it is nice to read some facts from someone who is evidently "certified on type" and can explain horse "systems".
But in any case, legal or not, I do not see how anyone can defend the practice of circling at 500ft over people, animals or property in this way. A/C have no business flying low over the countryside except for the purposes of takeoff/landing or where necessary to comply with airspace limitations. And if you have to fly so low you should always pass through the area as quickly as possible, allowing just the occasional 720īturn to wave at girl/boyfriends.
There is, though, a possibility of extracting a positive outcome from this sorry affair: If every flying club and horse club could arrange reciprocal open days perhaps both sides could understand each other better.
