While a family medical history provides information about the risk of specific health concerns, having relatives with a medical condition does not mean that an individual will definitely develop that condition.
The Disney Skyway was removed in November 1994 because it was too costly to make safety upgrades and prevent an incident. At Disneyland, the Fantasyland Skyway station remains, but the Tomorrowland station has been mostly removed. In 1998, Tokyo Disneyland closed their Skyway attraction and the Fantasyland station was removed to make room for Pooh's Hunny Hunt, while the Tomorrowland station was remodeled into a candy store.
The Skyway, one of the original Walt Disney World attractions, present when the park first opened in 1971, was an aerial tram (cable car) type ride, which took guests between the Fantasyland and TomorrowLand parts of the Magic Kingdom, on a ride that lasted for around 5 minutes.
