In the late 90s I worked the overnight shift on the ramp in Norfolk, VA (ORF), home of Ford’s F-150 production line. Ford was continuously working out the bugs of just-in-time inventory control, and so it was rare for an evening to pass without some classic (if not antique) cargo plane to pull up unannounced with a load of parts. No expense was spared to keep the production line running. The most memorable was a DC-8...taxied in, the pilot opened his cockpit window and dropped a paper grocery bag down to the ramp. I never did learn what was in the bag. It weighed maybe five pounds. Whatever it was, it warranted a DC-8 flight at 2AM.
