"May God stand between you and harm in all the empty places where you must walk."
- – Old Egyptian Blessing
Jack Maynard was an officer in Earthforce and a close friend of John Sheridan. Sheridan calls him "Stinky" while Maynard calls him "Swamp Rat." Maynard was Sheridan's first commanding officer, on the Moon-Mars Patrol.
Years later, Maynard served in the Earth-Minbari War. At one point, he shared an old Egyptian blessing with Sheridan that he would often repeat in subsequent years.
Maynard was assigned to the Cortez around 2254. He and his ship spent most of the next five years along the Rim mapping unexplored space. The last two years alone were spent mapping Sector 900. In 2259, they were called into the Euphrates Sector to assist in repairing a Jump Gate. Needing to resupply his ship anyway, Maynard decided to head to Babylon 5 when he learned his old friend Sheridan was now in command of the station. Maynard was glad to see Sheridan again, but was curious as to whether Sheridan truly enjoyed his new assignment, feeling he'd been "beached." In addition to catching up, Maynard also mentioned once seeing a glimpse of a strange alien ship.
After resupplying, the Cortez jumped back into hyperspace, but a catastrophic malfunction sent the ship adrift. Luckily, they were able to send a distress signal to B5, and a Starfury wing managed to bring the ship back to the station, marking the first time an Earth ship lost in hyperspace was recovered.
- Jack Maynard's sole appearance was in "A Distant Star"
- It remains unrevealed which side he took during the Earth Alliance Civil War, though it is possible that given the nature of his deep space assignment his ship was completely out of contact for the conflict.
- The script for "A Distant Star" notes that Maynard is sixty years old.
