The historic flight of the Phoenix took place on April 5, 2063. On that day, the Vulcan survey ship T'Plana-Hath was passing through the Sol System when it discovered a Terran warp signature. Following procedure, its captain Solkar had the T'Plana-Hath proceed to Earth to investigate the warp signature, and landed at the settlement in Bozeman, Montana from where the Phoenix had been launched. Solkar was the first to exit the T'Plana-Hath and meet Cochrane.
After Solkar gave the traditional Vulcan salute, Cochrane pulled out a shotgun and killed him. He then rallied the rest of the townspeople to board the vessel, appropriate any item of value and kill the rest of the crew. This action resulted in the early expansion of the Terran Empire, allowing Terrans to drastically increase their technological capability and begin a campaign of warfare and conquest. (ENT episode: "In a Mirror, Darkly")
His accomplishments were well-known, even almost 80 years after the fall of the Terran Empire. In 2371, Vash described Noonien Soong as a genius, comparing him to Cochrane and Richard Daystrom. (TNG - Mirror Universe novella: The Worst of Both Worlds)
- The short story Nobunaga stated that Hoshi Sato's predecessor as the monarch of the Terran Empire was named Cochrane. While it was never specifically stated, it is highly likely that he was one of Zefram Cochrane's descendants.
Spectre / Dark Victory Edit
In another permutation of the mirror universe, Cochrane was directly responsible for the founding of the Terran Empire. He chose to warn the Vulcans about the Borg threat, leading to Earth and Vulcan forming a military alliance which eventually evolves into the Empire. (ST novels: Spectre, Dark Victory)
In another permutation of the mirror universe in which the Terran Empire survived well into the 24th century, Cochrane's invention of warp drive was responsible for the Empire's first serious expansion. (TNG novel: Dark Mirror)
