Corrected entry: In the first episode, "Everything Changes," Gwen is told that "Captain Jack Harkness failed to report for duty" on 21 January, 1941. However, in "Captain Jack Harkness," Jack tells Tosh that the real Captain Jack Harkness will be killed in combat, taking down 3 Messerschmidts and getting the rest of his squadron safely back to base in the process the next day. Surely, at least one of his men would have reported that the Captain died a hero. If not, how can he fail to report for duty if he was in the air? (00:39:10 - 00:39:50)

Captain Jack Harkness - S1-E12
Factual error: When Gwen finds Toshiko's hidden message from 1941, she realizes that it was written in blood, and her flashlight reveals the bright red letters on the now-yellowed piece of paper. But after 60+ years, the iron in the blood would oxidize. The writing on the note should be rust-brown, not red. (00:33:40)
Captain Jack Harkness: Under normal circumstances, an exuberant Roman soldier would be my idea of a perfect morning.
Trivia: The hand preserved in a glass jar in the Torchwood HQ is the severed hand of Doctor Who which he lost in a duel during the Christmas special. The hand features quite prominently in episode 1 but can also be seen in the background in most episodes.
Question: If Owen and Toshiko were already working for Torchwood's Cardiff branch before Torchwood One collapsed, what were they doing in London at the time of "Aliens of London"? Surely there must have been another medic in the region.
Chosen answer: As long as Jack's been in charge of it, Torchwood Cardiff has had a different agenda than Torchwood One. Tosh and Owen were there to watch for signs of the 10th Doctor, however, it was the 9th that showed up when the ship crashed in London.
Correction: Gwen asks for information on a living man named Jack Harkness. The original Jack Harkness, the pilot, is confirmed as having been killed in combat - as you say, his squadron would have reported his heroic death. Being confirmed as deceased, there's no reason for the researcher to mention him. Torchwood's Jack Harkness, who took his name and who also served in the military, is the one who was listed as having vanished without trace.
