My son and I (ages 41 and 70) had done "flights" at this iFly and enjoyed the experience.
When I saw how many younger "fliers" there were, my wife and I took our grandchildren (ages 11, 8 and 6) to the facility, and they had a great time!
I have to admit, it is a little pricey, ~$70.00 per person for (2) one minute flights (this includes suits, goggles and training, plus the instructors accompanying each person during their flight). Of course there are optional add ons (pix, videos,higher flights,hats,t-shirts,virtual reality, etc.
You are first suited up, then given an instructional class to tell you what to expect, and explain the hand signals used for guidance during the flight. It is VERY loud, and earplugs are given out. Wind speed up to 165 mph, so no loose jewelry and longer hair should be pulled back.
There are generally ~6-8 in a group of fliers, and my group ranged from 6-70 in age.
Basically, you are in a vertical wind tunnel, with a net for a floor and ceiling, and the wind speed to get you in flight is adjusted based on your weight. Most of the time you aren't more than 6 or 7 feet above the floor net.
The suits that the fliers of all ages wear have handles on them, so that the instructors have control all of the time, and they don't get fancy; each flight is 1 minute, so much of the time in the first trip is just getting used to the noise and holding yourself horizontal. The second trip is somewhat easier; you know what to expect, and can relax and enjoy it more.
If you really like it and can afford it, advanced classes are available in which you can learn flips, turns, etc. I was happy just to do it once, for the experience; it beat jumping out of a plane and worrying about a parachute opening. Grandkids loved it..
