May 24, 1950. Holloman AFB, Alamogordo, New Mexico (BBU)
During an MX-674 Tarzon controllable vertical bomb test, Floyd Fannon and other USAF contract Land-Air, Inc., Askania theodolite crew members saw 8 unidentified objects then separately tracked and filmed 2 of the objects down the North American Aviation missile firing range. Cinetheodolite station P-8 filmed one object to the NE for 6 frames (1.0 sec) moving uniformly to the S from azimuth 38° 26' 59.2" to 38° 33' 59.2" and elevation 47° 32' 20" to 47° 25' 50". Cinetheodolite station P-10, located 5.6781 miles down range to the N (to azimuth 347.07723°) from P-8 and 7 ft higher, filmed another object, hence no triangulation possible, viewed to the E for 74 frames (14.6 secs) moving uniformly to the N from azimuth 86° 9' 9.2" to 85° 47' 9.2" and elevation 25° 48' 0" to 25° 7' 50".
