Main Characters in this Episode
- Goof (crew or equipment visible): When Jonas and Sam are investigating the device you can see the light bulbs inside the device.
- Col. Jack O'Neill tells paranoid veteran Vernon Sharpe (Jody Racicot), who sees aliens, that they were from "Melmac". When Sharpe asks, "Isn't that where ALF was from?" O'Neill says he never saw the show. This is an in-joke, since for most of its run, ALF was in the same time slot as MacGyver, which starred Richard Dean Anderson in the title role.
