Continuity mistake: When Mulder experiences his near-death trance state his body is lying, apparently lifeless, in a star spangled sky. As the camera tracks in on him the toes on his right foot twitch, just after Deep Throat begins to speak. The foliage covering his chest also changes position between shots. In the wide shot he is covered up to the armpits. But the first close up shows his chest is exposed. Then in later close ups it is covered again. (00:14:25)
Plot hole: Mulder is pulled from the escape hole previously dug by the hybrid aliens to escape the train car. When they pull him out they show alien bodies remaining in the hole. Mulder never revisits the train car despite knowing there's a high probability of finding hard evidence, in this case some actual bodies. There's no way Mulder would just assume there's no evidence remaining there and not go have a look for himself. Same goes for Cancerman who thought he had destroyed the evidence.
Chosen answer: Yes.
