About this episode

The episode discusses the critical role of weather forecasting in the success of the D-Day landings during World War II.

"If any blame or fault attaches to the attempt, it is mine alone." This is the end of the announcement Supreme Allied Commander General Dwight David Eisenhower had prepared in June 1944 in case the D-Day landings failed. He never had to deliver it, but the fact that he wrote it tells you all you need to know about how precarious the success of the invasion really was. And at the center of that uncertainty was something no army could control: the weather. This is the premise of the new major motion picture Pressure, the story of the small team of meteorologists trying to predict the unpredictable. Guest host Dr. Mark Jacobson sits down with the screenwriter of Pressure, David Haig, and the film's co-writer and director, Anthony Maras, to discuss how a simple weather forecast proved to be a critical piece of intelligence. *Note: It is Joan Clarke, not Joy.
