The plot aspect of Archangel being captured by enemy agents is very similar to Fallen Angel (1984), which aired 11 months earlier in November 1984. In the earlier program, The Firm did not send out an assassination squad after 48 hours, instead they were going to shut down his section after 36 hours.
The license plate on Archangel's Jeep is 'Firm 1'.
Archangel's limousine in Airwolf II (1985) also had the license plate 'Firm 1'.
