Fresh off of alien abductions, we are heading into alien flight territory. In Season 1, Episode 2: Deep Throat, we come up against the government and alien technology. This is about a pilot! (I know that the first episode of any show is a pilot, but the pilot episode still could have had a snazzy title).
The X-File: a swat team has found a test pilot, curled up, burned, and shaking in the corner of his bedroom. Pilots have gone missing in the past. Pilots!
At a restaurant, the perfect place to discuss FBI cases, Scully is surprised that Mulder wants to investigate this case since it seems to be following a line of test pilots going missing over the years. Rumor has it, they were shot down by Russians. Of course, Russians. Some things never change. This most recent case intrigues Mulder because it was de-prioritized without an investigation and smells of the paranormal. He calls it a paranormal bouquet.
