The U.S. drone war across much of the Greater Middle East and parts of Africa is in crisis and not because civilians are dying or the target list for that war or the right to wage it just about anywhere on the planet are in question in Washington. Something far more basic is at stake: drone pilots are quitting in record numbers. There are roughly 1,000 such drone pilots, known in the trade as “18Xs,” working for the U.S. Air Force today. Another 180 pilots graduate annually from a training program that takes about a year to complete at Holloman and Randolph Air Force bases in, respectively, New Mexico and Texas. As it happens, in those same 12 months, about 240 trained pilots quit and the Air Force is at a loss to explain the phenomenon.
