1995 John B. Dendy @ Natal, Brazil Air Force News Service (Oct. 26) “AF deploys to Brazil for first time since WW II” @ Usenet: sci.military.moderated (Oct. 31, 2004) Sysop Afpan (.(JavaScript must be enabled to view this email address)) “Air Force News Service 26oct95”: “We have flown everything as fragged,” Cantres said. “Today was the first day of flying and the box score reads 12 scored, 12 flown, 9.7 flying hours.” 2002 Pete Wilkie Flying Safety (US) (Oct.) “Situational Awareness [Lucky or Good?]”: Without both preparation and experience, tactical lessons and execution fall short of ideal. The mission may come off “as fragged,” but the learning curve remains stagnant. 2004 Rahul Singh @ Ambala, Haryana Times of India (Aug. 20) “IAF marathon flyers outpace the best”: They didn’t understand that when the Americans said “as fragged” they meant “as planned,” the Indian parallel for “hack” was “time-check” or that the US pilots called “fess up” to own up a mistake.
