When the CAA relaxed the rules on foot launched powered aircraft to allow take off and landing on wheels, it had me wondering what three axis aircraft may be possible. There have already been a few which fit the bill, although they are considerably less practical than a paramotor which could be stored in a wardrobe, or a weightshift microlight which could be rolled up and hung in a garage.
Here are a couple:
Birdman TL-1
Birdman Aircraft TL-1
Butterfly microlight

As others have said, getting training is a must. Just because something flies slowly, doesn't mean it will be easy. The Wright Brothers had years of experience with their gliders on deserted and relatively forgiving sand dunes before they attempted powered flight. There are plenty of people confined to wheelchairs for the rest of their lives who thought they knew better.
