This is the second and last episode (the first is the pilot) in which B.A. is referred to by his real first name - Bosco.
The plane (N26MA) is a 1939 Douglas DC3-G102A serial number 2169 still airworthy and located in Perris, CA.
The helicopter used for the escape (Bell JetRanger III 206B-III serial# 3363 N2044C) was also the Santini Air helicopter (Airwolf) sporting a different paint scheme and seen in other productions as well.
The creature costume that was used was the same one that was used in the Buck Rogers in the 25th Century episode The Crystals.
