Lana Lang, Superboy's friend from childhood into adolescence and then into adult life was the first person to suspect Clark Kent and Superboy was one and the same person. Her first appearance was in the September-October 1950 issue of SUPERBOY NO.10 in "The Girl in Superboy's Life." Afterwards in SUPERMAN 78/3 from September-October 1952, as an adult woman, she moves to Metropolis and works at the Daily Planet with Clark Kent, and even for a few days, lives in Lois Lane's apartment. Lana Lang as adult, is Lois Lane's chief rival for Superman's love in several adventures. In 1965 she becomes a TV reporter (SUPERMAN 177/2). In the post-Crisis version by John Byrne, Lana Lang is Clark Kent's close friend, being the first person who knows his secret identity as Superman.(see)
As can be determined from the above history of Lana Lang, you can see, as a comic book character in Superman and Superboy comics, she did not show up for the first time until Superboy No. 10 with a cover date of September-October 1950, some two years AFTER the event with the cab-forwards and the flight out of the dirt airstrip south of Reno as mentioned in both June Lang and Riding the Cab Forewards linked below. As written in both it seems as though I put the two Langs, June and Lana, together at that moment at that same time. It was after I became aware of Lana Lang that I was able to recall backwards that the woman was June Lang. The fact the woman may have been the movie actress June Lang on the plane was brought up to my grandmother by my uncle early on, he knowing that my mother and June Lang had danced together as children professionally. Between my grandmother, uncle and I, the whole June Lang thing was kept alive on-and-off long enough for me to make the connection with Lana Lang on my own sometime in the 1950s, the 12 year old boy or so that I was, and from there I extrapolated it clear up to the point I felt I knew about the connection my whole life.
