Harley Random and others can be seen at the end of a runway with her ID badge clipped to her pants pocket. In SIDA (Security Identification Display Areas), such as airport ramps, runways, etc. you are required to display the badge, among other things, above the waist. (The others had no visible badges.)
Frank John Hughes' caracter, "Henry Engels", says that the stowaway has "two bucks Grenadian on him" while looking in the bills section of the wallet. First, Grenada does not have its own currency. Nine Caribbean countries, including Grenada, are members of the Organisation of Eastern Caribbean States and the majority of them, again including Grenada, share the Eastern Caribbean Currency (EC). Secondly, if the proper currency had been referenced, the character would have been incorrect in looking in the bills section of the wallet. Since the late-1980s/early-'90s, the EC $1.00 has been a coin, not a bill. However, the color of the bill was red which is the color of the paper in the wallet.
