Faced with the impossibility of outdoor skydiving, Singapore has not simply ignored the demand for freefall; it has innovatively substituted it. The result is iFly Singapore, located at Sentosa’s Siloso Beach. Opened in 2011, it was the world’s largest themed indoor skydiving facility at the time. This vertical wind tunnel generates a column of air at speeds of up to 180 mph (290 km/h), perfectly simulating the freefall portion of a skydive.
