The first U. S. work dedicated to the medical aspects of military pilot selection. According to the National Museum of Health and Medicine, this manual was written by William Holland Wilmer, then director of the Medical Research Laboratory at Mineola, Long Island (1917). This placed Wilmer at the forefront of training for flight surgeons and in the classification of pilot candidates as they used novel devices and instruments to simulate high-altitude conditions. He pioneered efforts to produce oxygen delivery systems to pilots. CHAPTER I: Aviation and its medical problems. CHAPTER 2: The selection of the flier. CHAPTER 3: The classification of the flier.
