PURSUE-RELEASE-02 serial 43ad166c-06e5-49d1-b05f-c5eeffc392df is a multi-document file containing two distinct sets of records from 1949. The first is a Secret letter dated 7 April 1949 from Lt. Col. Richard W. Klime, Commanding Officer of Detachment D, 1100th USAF Special Reporting Group at Camp Campbell, Kentucky, responding to a security inspection report from Sandia Base, Albuquerque, New Mexico. The letter details corrective actions taken, including amending guard orders to close the electric gate between 1700 and 0700 hours, replacing bolts with locks on inspection access gates and bridge inspection ports, installing jeep radios, and establishing radio communication with Camp Campbell Military Police. The letter also notes ongoing difficulties with erosion control, with interim repair costs estimated at approximately $20,000, and requests that the required monthly reporting be discontinued since all other deficiencies had been resolved [PURSUE-RELEASE-02/43ad166c-06e5-49d1-b05f-c5eeffc392df].

The second set of records concerns a study titled "An Attempt to Collect Airborne Particles Associated with the Fireball of July 24, 1949," authored by W. D. Crozier and Ben K. Seely of the New Mexico School of Mines. A fireball was reported over the general neighborhood of Socorro, New Mexico at 8:26 p.m. on July 24, 1949, and the researchers subsequently made systematic airborne particle collections at Socorro from July 25 through August 1 using impactment equipment coated with a rubeanic acid reagent to detect copper, nickel, and cobalt. The collections found copper-bearing opaque particles and three apparently perfect spherical cobalt-indication particles twelve microns in diameter in the July 26 afternoon collection. A separate series of collections on Highway 84, seventeen miles north of Highway 66, also showed a large number of copper-bearing particles in one sample, though the passage of two automobiles during that collection was noted as a complicating factor. The file also includes a cover letter dated 10 August 1949 from the Research and Development Division of the New Mexico School of Mines to Dr. Lincoln LaPaz of the University of New Mexico Institute of Meteoritics, transmitting copies of the report at his request [PURSUE-RELEASE-02/43ad166c-06e5-49d1-b05f-c5eeffc392df].
