The Quantum Slipstream Incident

The USS Voyager crew constructed their own quantum slipstream drive using benamite crystals, overcoming some difficulties in their first attempt. Despite promising potential results, Tom Paris discovered a phase variance in the slipstream threshold, threatening to overload the drive's quantum matrix and destroy the ship. Harry Kim realized that the smaller size of a piloted shuttle leading Voyager could allow early phase variance detection of the complex, dynamic slipstream threshold for the larger ship. These advance data and corrections would help Voyager safely navigate the quantum slipstream. During the test flight, with Chakotay piloting the Delta Flyer, Kim sent wrong correction values to Voyager, causing the slipstream to unexpectedly collapse ten light years near the Alpha Quadrant. Voyager crashed on an class L planet in the Takara sector, killing all hands, including Captain Kathryn Janeway – however, ahead of Voyager in the stable Delta Flyer slipstream, Kim and Chakotay survived the disastrous test and returned to Earth, filled with guilt.
