Factual error: Enid, the telegraph operator, exclaims that "He is sending an SOS." However, in the 19th century, distress calls did not include the letters "SOS," It was not until the early 20th Century that SOS was chosen as the international distress call.
Factual error: When the 747-aircraft of the fake German airline is being shown, you can see the German flag on the plane. But you also see an "N-xxxxx" registration which stands for USA. If it were a real German plane, it would have a "D-xxxx" registration.
Factual error: Any time FBI agents enter Mexico, they are always armed. Mexican law prohibits U.S. Agents from bringing weapons into Mexico.
Suggested correction: The show is set in the early 1900's, which is the early 20th century. By the time this event transpired, SOS would have been established as a universal distress signal.
The show starts in 1895 and by season 2, it was still the 19th century and before Germany adopted SOS in 1905.
