A page from a 1944 personal letter written by an Army Air Forces trainee, part of the Margaroli B-24 belly gunner collection, describing the harsh realities of high-altitude flight training -- temperatures of 20 to 30 degrees below zero at 25,000 feet, constant oxygen mask use, and the danger of bare skin touching frozen metal. Letters like this provide a rare, personal window into the training endured by B-24 Liberator crewmen before they faced combat over Europe or the Pacific. Project: 218355
