Voyager encounters another Federation starship in an episode that aired on this day in television history.
“Equinox, Part I” is the 5th season finale of Star Trek: Voyager. Written by Brannon Braga and Joe Menosky (with story by Braga, Menosky and Rick Berman), it first aired on UPN on May 26th, 1999.
In the episode, the crew of Voyager are surprised to hear a distress signal from another Federation starship, the small scout ship, Equinox. They find the ship battered and under attack by strange lifeforms, but manage to save it in time. The crews are glad to see each other at first, but Equinox is holding a dark secret.
“Equinox” ended in a cliffhanger that would resolved when the sixth season of Star Trek: Voyager debuted later that year in September.
