I keep thinking about building an aeroplane for our cat, and teaching him how to fly. It's a bit of an unrealistic proposition though, so I'll probably make him a little motorbike first and start him off that way
I used to work for a now defunct UK motorcycle dealership, and the managing director ( who was a bit of a 'character' to say the least ) owned a light aircraft. There was a stretch of open countryside at the back of the main shop where I was a mechanic and one day he flew over to demonstrate to us what an ace pilot he was, diving under the power lines crossing the fields ( about 25ft AGL I'd guess )
Someone got the registration of his aircraft though, complained, and the CAA took his licence away from him. I didn't have a huge amount of sympathy. While the world needs nutters who push the envelope, but I'm not sure it needs nutters who might crash an aeroplane into your house just because they want to show off
