(1) The first three Tommy Tomorrow adventures (Real Fact #6, #8, #13) contradict all subsequent stories, and thus can be considered apocryphal. Beginning in this issue, his fourth appearance, Tommy Tomorrow is established as a Colonel in the Planeteers, and his adventures are said to occur exactly 40 years in the future. From his fifth appearance in Action Comics #127 through Action Comics #147, his adventures continue to take place exactly 40 years in the future. However, beginning with Action Comics #149 and continuing throughout the next dozen years, his adventures occur exactly 100 years in the future (Action Comics #148 mentions no year).
(2) The events of this issue occur between page 2 panel 2 and page 2 panel 3 of the Tommy Tomorrow story in Action Comics #127.
(3) Corporal Larry Winters states that Tommy Tomorrow has a wife and kids.
