Hi,
remember a training flight with police dogs - they were tested and trained for helicopter transport.
We used the Bo105 at that time and the dogs juft jumped in with their handler, we did a short flight and after that, the dogs went out and catched a target (man with a covered arm).
On one of the flights a big evil looking german shepard dog just placed his nose on my shoulder and enjoyed the good forward sight....luckly I had a helmet on.
And yes, dogs canīt judge the height - and some handlers canīt even.
So one dog jumped out at about 15 feet with still some speed on. The dog bounced and tumbeled and then went straight for his target - so better donīt mess with police dogs.
Greetings Flying Bull
