This is the first time that Jeannie is officially introduced to NASA personnel and the world as Tony's fiancee. However, Dr. Bellows had met Jeannie on season one's Too Many Tonys (1965) and both Dr. and Amanda Bellows had brought her to their home on season three's Divorce, Genie Style (1968), and in both episodes they had known her as "Jeannie". Strangely, the Bellows seem to be experiencing memory lapses here (could Jeannie have arranged it?).
Tony and Roger leave Alaska in a USAF T-38 Talon, a tandem seat trainer jet. It was the first supersonic trainer jet, introduced in 1961.
