I just think of this as a great way t get a feel of the real deal. I mean it's not easy to replicate such an intense experience with modern technology. Somehow they managed 500,000_ downloads which shows that there is a market for something like this. Many of them probably were people who were too afraid to try n actual sky diving experience.
What we really need is WIND!!! Without wind the experience is going to feel cheap ad fake. Wind is ha sells the experience. Guess we'll have to let it to the future developers to make those artificial wind makers.
