February 13, 1957 — Lincoln, NE
2:30 a.m. The USAF operations director and three tower controllers at two radar sites within Lincoln AFB [now Lincoln Airport, Nebraska], the GCA and NCOIC, track several targets flying behind an airliner at a distance of 5–6 miles and traveling twice as fast. There is no IFF response. The objects hover and move at high speed. One splits into two objects, another executes an 180° turn. The radar blips are the size of a B-47. [Eberhart]
