This aircraft type, the Lockheed F-104, was not identified by name on screen, but is derived from visual identification from its appearance in "Tomorrow is Yesterday". It was also identified as this type of craft in the Star Trek Concordance. The footage used on screen and the still shown here are from George AFB, California.
Starfighter FG-926 – originally the registry for "Bluejay 4", before it was changed in the remastered version – was prominently featured in CGI by Douglas E. Graves on the November spread of the Star Trek: Ships of the Line (2012) calendar, pictured on the left. The same scene had already been featured previously in two earlier outings of the same calendar series; by Robert Bonchune for his December spread in the 2003 edition – though it could not be discerned which F-104 was seen – whereas Aurore DeBlois depicted the disintegration of Bluejay 4 in the February spread for the 2007 edition.
