Model Airplane News a national security risk?

Holy smoke! Model Airplane News and the CIA? In the March 1958 issue, a scale 3-view drawing by Bjorn Karlstroan of the super-secret Lockheed U-2 spy plane was featured in the Planes Worth Modeling column. This was long before Francis Gary Powers was shot down (May 1, 1960), and the government was forced to admit that the U-2 aircraft actually existed. Hmm. The Model Airplane News article observed: “An unconfirmed rumor says that U-2s are flying across the Iron Curtain taking aerial photographs.” It is said that government officials investigating the release of classified information visited the Model Airplane News offices on 5th Avenue in New York City.
