Titan's Turn

Titan's Turn was a dangerous shuttlecraft maneuver sometimes performed by Starfleet pilots on the Jovian Run. Upon entering Saturn's planetary system, the pilot would accelerate almost directly towards Titan, the largest moon of Saturn, and then grazing the moon's atmosphere before turning sharply around the limb of the moon at 0.7 c. Geordi La Forge and Edward Jellico were both experienced at performing Titan's Turn during their stints as pilots on the Jovian Run.

Because of its unsafe nature, the maneuver was banned by Starfleet.
