While Enterprise is investigating what appears to be a dark matter nebula, Archer receives news that A.G. Robinson, his old rival in the early days of the NX test program, has died. During a shuttlepod mission into the dark matter phenomenon, Archer reminisces to T'Pol about the time he and Robinson were pilots competing for the honor of being the first to break the Warp 2 barrier.
Set before the events of "Broken Bow", the episode will reportedly revolve around the testing of the Warp 5 engine. However, the original test in space failed, destroying the ship, although the pilot managed to survive. In order to test the engine, which they believe will work, Tucker helps Archer take the NX-Beta on a test flight - without Starfleet's knowledge.
Will feature cameo appearances by the USS Enterprise's "Sailors of the Year", continuing a tradition begun during last year's "Desert Crossing".
Principal photography on "First Flight" ran from Monday, March 10, to Tuesday, March 19. The scenes shot on the first two days utilised regular NX-01 sets, before production moved to the new locales constructed for the flashback scenes. These included the NX-Hangar, NX Mission Control and the 602 club, frequented by Starfleet officers and home to Ruby, the waitress.
