70 Years Ago: F-86s and MiGs over Korea

On December 17, 1950, the first known aerial combat between swept-wing jet fighters took place in the skies over Korea. The Russian-built Mikoyan-Gurevich MiG-15 had been recently introduced and its speed and maneuverability caused trouble for the United States and in response, the North American F-86 Sabre was rushed to Korea. Ward Hitt, Jr., a member of the 4th Fighter Interceptor Group, chronicled the early days of the F-86 in combat in a detailed scrapbook.

Discovery Rupes (left), named for the ship HMS Discovery, shown here in a MDIS high-incidence angle image mosaic, was first imaged by Mariner 10 in the mid-1970’s. Beagle Rupes (right), a bow-shaped fault scarp, was initial imaged during MESSENGER’s first flyby.
