I can remember decades ago reading the wartime history of Group Captain James Stagg, the man who might have destroyed the Normandy invasion fleet in 1944. He was the senior meteorologist working directly to Gen. Eisenhower. There were three different met teams attempting to forecast the weather in the Channel - arguably the worst bet of any time! There was a American team, an Admiralty team and a Met office team, the latter commanded by Stagg.
Originally, the invasion should have been launched on the 5th June but despite the potential for damaging disruption, Stagg's interpretation of the information available made him urge Eisenhower to delay. The other Brit team agreed but the American team, using very new methods of analysis, disagreed strongly and urged the invasion on. The Brits were right and the Americans wrong but Stagg went further than his comrades and forecast a slight lull in the weather during the 6th June which would allow the landing to take place. I simply cannot conceive the pressure this must have exerted on his mind.
Well, as we all know now, James Stagg was right and his moral courage in persevering was simply beyond description. You can read more at The Mail.
