So after a career in flying for the RAF, many pilots would go to the flight surgeons when they were done flying with complaints about their backs. Many of them had backs and spines that were in real terrible shape after a career of flying military planes. It was because of this that the Flight Surgery/Medical wing of the RAF got interested in doing comfort and ergonomic research into pilot seats. The company was trying to impress us with their technical expertise by telling us that they were using the results of these RAF studies to better design seats (or design better seats).
Well, what did I find interesting in all this? The pilots never complained until they were retiring from flying. You see, no pilot goes near a flight surgeon for any such reason as back pain/trouble for fear that they will grounded and their flying days deemed over.
