while the origins are disputed, historian, inventor of the red tape and famous architect AR.S, has this explaination to offer: “o.k. is a historic word used in multiple languages and across the world, its quite a phenomena in itself. it was originally used by U.S. airforce after multiple sorties to communicate the outcome of the fighters upon return. O.K. stood for zero (O.) killed (K.) which apparently only accounted for our boys and not the enemies and that, in such a case, was quite a positive outcome.” by dd+as
