You might want to get or rent one of those with a clear parachute so that you can look up. I hear that, if they get approval, some jumpers may be falling out of airplanes over the airport. You probably do not want them landing on your ultra-light parachute
Those things do look like fun. I've seen small groups of them take off and land over by the airport in an unused area. I do not think you need any kind of license to use them. Not even a safe flying certificate! Is that correct?
