April, Robert T.
A rugged, heroic-looking human male born in the year 2195, Captain Robert April was the first commander of the U.S.S. Enterprise NCC-1701 when it was launched in 2245 for its initial five-year mission. He was succeeded by Captain Christopher Pike.
On stardate 6770.3 (2270), April was a senior Starfleet commodore on his way to the Babel planetoid where his formal retirement ceremonies were to be held, per Starfleet regulations mandating that human officers retire at the age of 75. Because of their already advanced ages, Commodore April and his wife Sarah weren't debilitated by the reversed time-flow of the parallel antimatter universe in which the Enterprise became temporarily trapped during the voyage to Babel; instead, they were returned to the prime of their lives. The heroic manner in which the Aprils took command of the starship to get the vessel safely home after all other personnel aboard had grown too young to handle the controls motivated Starfleet to review its mandatory retirement rules, and to keep Commodore April on as the Federation's ambassador-at-large. Because neither Robert nor Sarah April harbored any regrets over how they had spent their lives, they opted to use the Enterprise's transporter to return them to their normal ages following their return from the antimatter universe.
