*Dates in Flight on Titan are inconsistent with themselves and the rest of Weinbaum's planetary stories. The principal date given is 2142, and the main story takes place in the following year; however, 2030 is referred to within the story as if it were a recent date, and references to the events in Flight on Titan in other stories indicate that they must have taken place before both The Lotus Eaters and The Mad Moon, i.e. in the 21st and not the 22nd century.
