Corrected entry: At the crash site of Flight 549, Scully says "The plane came in nearly vertical at 300 miles per hour." yet the fly-over view of the debris field shows it spread out over hundreds of feet. Unfortunately, on 9/11 we learned when large commercial aircraft crash straight into the ground, they leave massive, smoking holes. First responders at Flight 93 were not even aware they were looking at a crash site.
Corrected entry: After Mulder retrieves the metal spike right after stabbing the alien bounty hunter, he chases Jeremiah, who has boarded a boat. The shot cuts back soon after to the bounty hunter's body and the spike can still be seen in his neck.
Correction: The metal spike Mulder picks up belongs to the alien bounty hunter. You see him holding it before Mulder stabs him.
Corrected entry: When Mulder stabs the alien bounty hunter and the body rolls down the hill, we see the metal spike in the back of his neck, surrounded by his green acid blood. Yet when Mulder climbs down after it, it is suddenly lying on the ground away from the body.
Correction: The metal spike he picks up belongs to the alien bounty hunter. You see him holding it before Mulder stabs him.
Corrected entry: Misty finds the cabin Jane was in open, however when Jane went to the toilet, she locked the cabin. Because of the bees Jane could not have unlocked the doors. (00:02:55)
Correction: In fact, Jane managed to open the cabin's door even though she was attacked by bees.
Corrected entry: When the repair man looks down from the pole at the clones, they all have shadows but the pole doesn't have a shadow.
Correction: The pole does have a shadow, but it's just out of camera range.
Corrected entry: Eddie's ability to shape-shift is attributed to every muscle in his body being striated. While that's a reasonable explanation as to how he can change his face, it doesn't explain how he is able to change his hair. He has short hair and is balding, but when he mimics Mulder, he is able to match Mulder's longer and thicker full head of hair.
Musings of a Cigarette-Smoking Man - S4-E7
Corrected entry: The CSM wants to publish his book. It is quite odd that he has to submit it to some publishing houses and suffers from being ridiculed. Using his practically infinite power he could publish or just order to publish the story whenever he pleases. (00:23:10)
Correction: CSM's writing means a great deal to him, and while he must certainly be aware that he has the power to have his stories published, it's highly likely that like many creatives, he simply wants them to be wanted on their own merit.
Musings of a Cigarette-Smoking Man - S4-E7
Corrected entry: This episode contradicts the season 2 episode "Apocrypha" where young CSM was seen in the 1950's with Bill Mulder as already a shadowy agent and smoking. This episode has CSM still a young man and not part of the Syndicate in 1963, and does not smoke yet. Also this episode fails to mention anything about the conspiracy with an alien species which is one of the key features about the CSM.
Correction: Melvin is simply guessing at some of the details, he probably got some of those incorrect details from the story that Carl Gerhard Busch wrote, which is because the main character is based on himself, and how would you keep your involvement in an alien conspiracy hidden from the public if anyone could find out who you are?
Correction: This whole episode is based solely on Frohike's guesses about CSM, so obviously, he was wrong on some details.
Correction: The appearance and shape of a crash site depends on many factors, such as the exact angle of impact, density and composition of the ground, landform, airplane construction, amount of fuel, and more. Since we have virtually no information regarding these factors, the comparison between Flight 549 and Flight 93 seems to be far-fetched.
