After a really long hiatus, “Agents of S.H.I.E.L.D.” is in a summer season. Production of a show like this costs a lot of money, and visual effects are carefully planned, down to clips that might only be seen for a few seconds.
But somehow, they can’t afford a simple fact checker or continuity supervisor for the little things. This is from the episode that aired May 31.

This is at least the second reference to Iowa (or “Iowa”?) in the show. Weirdly, both episodes also had a Burning Man reference.
