All-Star Squadron #17 January, 1983.
On January 25, 1942: Five All-Stars (Commander Steel, Firebrand, Johnny Quick, Liberty Belle and Robotman) catch a ride on Wonder Woman's Invisible Plane, from Virginia to New York City, where she drops them off, literally, at Robert Crane's laboratory in Queens. Diana then flies back to Washington, D.C. to visit Steve Trevor at a military hospital there. At Crane's lab, the team meets Dr. Chuck Grayson and his fiancée Joan Carter. Joan considers Robotman a hero, because of an earlier rescue; Joan is also formerly the fiancée of the late Dr. Robert Crane, and does not know his secret identity.
