IThe British Royal Flying Corps’ wartime research demonstrated the importance of supplemental use of oxygen to pilots flying combat missions. The air service turned to Siebe, Gorman, and Company, English pioneers in the design and production of respiratory equipment for miners and divers. The company produced the first practical military aviation oxygen breathing system for the RFC although it was too heavy for use in early military aircraft. LtCol George Dryer of the RFC Medical Branch soon developed a more practical and lightweight system.
