(covers information from several alternate timelines)
While trying to feel "alive" in 2375 after learning of the destruction of the Maquis, B'Elanna Torres would occasionally skydive from a shuttlecraft in the holodeck with the safety protocols off. If the program was interrupted mid-fall, a force field would move her from a horizontal to a vertical position. (VOY: "Extreme Risk")
Background information Edit
James T. Kirk's orbital skydiving attempt was intended to be the opening scene of Star Trek Generations but it was cut from the film. It does appear in the Special Edition DVD and the novelization of the movie. The suit that Torres uses is a re-use of the one that Kirk used. Orbital skydiving is also mentioned in the novels Worlds of Star Trek: Deep Space Nine, Volume 1, Preserver, and Captain's Peril.
