One neat thing is that because you move with the breeze, you don’t feel any wind. Nor was there any perceptible motion that might make a person get airsickness. It was very calm overall. I would definitely do it again.
However…my sister did it back in 2007 and said that the wind picked up so much after they took off that they landed a few miles away from where they’d planned, did a hard landing, and were then dragged along the ground for 100 feet.
