At iFLY, “indoor flying” means something way cooler than jumping on your bed at home. There are helmets involved. Here’s how it works: you show up, suit up, and go through an orientation lesson with expert instructors before lifting off in an air column powered by giant fans. The column is forceful enough to simulate the experience of freefalling through the sky, even though flyers are just a few feet off the ground. As with outdoor skydiving, the freefall experience lasts for about a minute but with the earn your wings package flyers get two flights, and may be able to execute turns and tricks at the instructor’s discretion.
