Bluebook Case number is 6507, evaluation is "Unknown"

The case is listed in Dominique Weinstein's ACUFOE catalog:

59.09.13 -
USA Bunker Hill AFB, Indiana
PM a Mooney + a USAF T-33
pilots + 2 control tower operators
a white pear-shaped object, metal looking, with a tail maneuvered during 3 hours

Basically, it seems to be the same information as Don Berliner, safe:

GR means that the object was tracked by ground radar. G means that there were ground witness(es).
X means that there were more than one plane involved. 342 means that the source is Don Berliner's
listing of summaries of Bluebook unknowns.

Some information on the sighting location I gathered:


Later, Grissom AFB. Was officially opened 1 July 1942 by the U.S. Navy as Bunker Hill Naval Air Station. Following the Korean War, Bunker Hill was closed by the Navy. Bunker Hill Air Force Base was formally opened in June 1954 as a Tactical Air Command (TAC) Base and was home to the 433rd Air Base Squadron and the 323rd Fighter-Bomber Wing. In 1955, the 319th Fighter Interceptor Squadron joined the base along with the Strategic Air Command (SAC), and the 8th Air Force claimed jurisdiction in September 1957. In May 1959, the 305th Bomb Group, with B-47's in tow, arrived followed by KC-135 Stratotankers later that same year.

It is located in western Miami County (a small portion of the base extends into eastern Cass County), approximately 2 miles west of the town of Bunker Hill. The site is currently an U.S. Air Force Reserve (AFRES) military installation.

305th Bombardment Wing (Strategic Air Command), activated on 2 Jan 1951, using mainly B-47 Stratojets bombers in 1959, completed conversion to Convair B-58 Hustler delta winged supersonic strategic bombers, world's first production
supersonic bomber, in 1961.

The Strategic Air Command (SAC) assumed control of the base in 1957 when it became the home of the 4041st Air Base Group (4041 ABG). 

Sep 1957: 68th Aerial Refueling (M) Squadron (SAC), using Boeing KC-97L Stratofreighter propeller driven tankers.

From 1957 to 1959, preparations for mission changes at the base included the installation of advanced refueling system capabilities and the placement of fourteen 50,000-gallon underground storage tanks. In 1959 the 4041 ABG was redesignated to 305th Bombardment Wing. Aircraft operations of the 305th Bombardment Wing consisted of maintenance and operation of the B-47 bombers, followed by the B-58s. Additionally, in spring 1959, the base received its first KC-135 Stratotanker, which led to its primary mission change as home to a refueling wing. 

It converted from KC-97 to KC-135 tankers in 1959.

552nd Fighter Bomber Squadron Activated on 8th April 1956 at Bunker Hill AFB IN with F-86F. Squadron converted to F-100D in 1957.

The 453rd FBS was activated in August 1955 with F-86Fs at Bunker Hill AFB. The squadron then converted to F-100As in March 1956.

454th Fighter Bomber Squadron  The 454th FBS was activated in August 1955 with F-86Fs at Bunker Hill AFB IN. The squadron then converted to F-100 as in March 1956. Assigned 323rd FBGp throughout.

305th Air Refueling Wing:

In June 1959, the wing moved to Bunker Hill (later, Grissom) AFB, Indiana. The wing converted from KC-97 tankers to KC-135 tankers in 1959 and from B-47 to B/TB-58 bombers in 1961.

As the spring of 1959 arrived, the 305th aircraft headed north to their new home at Bunker Hill. A few months later, the wing began converting from the prop-driven KC-97 to the all-jet Boeing KC-135 Stratotanker, extending the wing's global reach.

Beginning in October 1958 through the next 32 months, the pilots of the 319th Fighter Interceptor Squadron at Bunker Hill AFB flew thousands of accident-free hours, even during the transition from the F-89J to the F-106 aircraft.
