Not listed among the original BB Unknowns, this case IS listed in the Comprehensive Catalog of Project Blue Book Unknowns, by Brad Sparks. Very little can be found regarding this incident apparently because the Air Force claimed "No conclusions. Report too late to investigate". However this much was found:

Sandia Mtns (Kirtland AFB?), NM. 4:30 PM (MST). (McDonald list, BB Rep 7), 15 minutes. Dull aluminum object, shaped like a flattened oval and as large as a B-29 fuselage. 150-200 mph and stationary. 10,000 feet. AF officer.
