When a friend happened to spot a surveillance flight over his neighborhood, it led Sam Richards, an independent journalist, to uncover a fleet of secret airplanes registered to fake corporations apparently created by the Department of Justice. While their purpose remains unknown, Richards has uncovered 100 of the aircraft and traced regular flights over major American cities. Richards, who writes under the nom de plume Sam Renegade, first published his findings on his Twitter account, @MinneapoliSam, before gathering them into a report on Medium. In his report, published on Monday, he outlines how each of the planes is registered to a fake corporation with a three-letter acronym for a name, such as “OBR Leasing,” which doesn’t seem to otherwise exist as a viable business from Internet or public records searches. Richards reveals that dozens of these aircraft, from front corporations like “FVX Research” and “KQM Aviation,” are registered at the same Bristow, Virginia, post office boxes used for planes which are openly registered to the DOJ.
