Subrata Roy, an aerospace engineer from the University of Florida, recently submitted a patent application for an aircraft that just happens to come in the shape of a flying saucer. Dubbed a “winged electromagnetic air vehicle,” or WEAV, the battery-powered prototype is designed at less than 6 in. across. Even so, Roy insists that the mini sci-fi mobile could be built full-scale for missions like atmospheric surveillance—and that’s got NASA and the Air Force interested.
