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)

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.
