July 24, 1949; Mountain Home, Idaho (BBU 483)
12:03-12:13 p.m. Henry Clark, manager of a flying service, flying a Piper Clipper at 19,000 ft, saw 7 delta-shaped objects, 35-55 ft in span, 20-30 ft long, 2-5 ft thick, light colored except for a 12 ft diameter dark circle at the rear [center?] of each, with a flat top surface and a 2-5 ft high dome, sharp needle nose, flat tail, outer panels oscillated then disappeared. Objects flew in a tight formation of 2's with 1 behind, and made a perfect, but un-banked, right turn about 1,500 ft ahead and 500 ft below with no wake turbulence, displaying decreasing smooth oscillations, then turned right again passing the aircraft at about 450-500 mph. Clark's engine ran rough during the sighting, and on landing was found with all spark plugs burned out. (Berliner; cf. NARCAP) 10 mins
