Aug. 31, 1950; Holloman AFB, Alamogordo, New Mexico (BBU)

10 a.m. ­ 1 p.m. (MST). After V-2 missile launch no. 51, Project TWINKLE Askania theodolite crews tracked and filmed multiple objects sporadically several times from several different directions at very high speeds over the course of 3 hrs. Askania cinetheodolite station P-5 filmed object with major axis varying from 8.65 to 13.243 arcmins (0.1442° to 0.22072°), minor axis 3.493 arcmins (0.05822°), one frame per second 60 cm focal length camera, 35 mm color film. Tape recording of audio reporting. Frames 593 and 595 (2 secs of nearly 10 mins? of film of object) show elevation angle changing from 53°44' to 52°38' at a rate of 0.37°/sec. Attempted interception by four F-86 jets from 93rd FIS, Kirtland AFB, for 1 hr failed to locate objects, which apparently returned after jets left. Cinetheodolite observers noted object with definite shape and 3-D depth but indistinct or not sharp edges, no smoke or trail, object seemed to “rock or oscillate,” lost when observer looked away to get angle reading.
