LIFE had to throw out 7 million unreleased copies of their magazine 50 years ago today, following the assassination of John F. Kennedy. On the cover of the issue that never made newsstands? Navy quarterback Roger Staubach.
The LIFE management put an immediate hold on the trucks that were to deliver the magazines to newstands across the country. When it was announced that President Kennedy had died, the company recalled all of the magazines and worked feverishly to add a new cover (with a close-up of JFK) and add assassination-related material.
Staubach would of course go on to serve in Vietnam, win two Superbowls, and be inducted into the Hall of Fame.
