I couldn’t track down the True Magazine article but there are a few short summaries 'out there' in cyberspace…
The following has been taken from
roswellproof.homestead.com

Another theodolite station filmed one of the objects
Within the above article is a link to the

May 24, 1950. Holloman AFB, Alamogordo, New

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
