This is a popular training method for competitive skydiving, and is also just a heck of a lot of fun. This simulation of skydiving uses the air blast from a propeller to blow you upward and keep you aloft inside a vertical wind tunnel.
Also known as “bodyflight,” windtunnel skydiving simulates the physics of a freefall, yet it’s a perfect alternative for someone who’s afraid of heights. Windtunnel skydiving also has the advantage of being suitable year-round, regardless of weather conditions.
It’s the closest thing to being able to fly (and of course, totally safe)! What's holding you back from making this part of your stag party in Budapest?
PS: It's perfect if your stag can't man up to do the tandem skydiving jump.
