Pima Air and Space Museum
Rare and Unique Aircraft
The museum has an
unusual selection of rare and unique aircraft. Some of these
are one of a kind aircraft, while others are rare. Here are
some of them.
Starr Bumble Bee, the worlds smallest
biplane to ever fly. It first flew on January 28, 1984 to
become the smallest aircraft to ever fly. The record was later
beaten by Roberts Starr's former partners in a monoplane. A
smaller aircraft, the Bumble Bee II set another record in 1988
that was destroyed in a crash not long after setting the
record.

McCullough HUM-1. It was designed as a 2 seat utility
helicopter. Three prototypes were built for the Army and 2
were built for the Navy. Neither service has a use for them.
The civil market was also indifferent to the MC-4 (civilian
version) and the design was scrapped.

Lockheed D-21B Reconnaissance Drone. Little is known about
this drone. It first flew in the mid 1960s, flown from an
SR-71 and later a B-52. Several missions were flown before the
program was scrapped in 1971.

Lockheed SR-71A Blackbird. The aircraft's unique shape make it
easily recognizable. The Blackbird holds many speed and
altitiude records, including a flight from Los Angeles to
Washington DC in 1 hour, four minutes and 2 seconds. Made of
mostly titanium, it was a technological leap when it was
introduced and is still considered advanced. The top speed of
the blackbird remains classified.

Columbia XJL-1. It was designed to replace the Grumman J2F
Duck, but did not meet expectations and suffered from a number
of structural failures. Of the three that were made, this is
the only survivor.

North American F-107A. It was designed to meet the requirement
for a USAF all-weather fighter bomber. It lost out to the
Republic F-105. Two of the F-107 prototypes were sent to NASA
after testing for control system experiments for the X-15 and
for high speed research flights.

Douglas B-18B Bolo from the 25th Antisubmarine Wing, 4th
Antisubmarine Squadron at Langley AFB, Virginia. The B-18 was
based on the DC-2 airliner using similar wing, tail and
engines. They were obsolete when WWII began, so they were
outfitted with RADAR and magnetic anomaly detection gear to
locate submarines in the Caribbean and Atlantic through 1943.

Lockheed YO-3A Quiet Star used by the FBI. They were first
used in Vietnam to track troop movements of the North
Vietnamese. Because of it's design, it is not heard from the
ground when it is flying at 1,000 feet. After Vietnam, the
YO-3s were used by NASA for noise studies, Louisiana
department of Fish and Wildlife to track poachers and by the
FBI.

Sikorsky S-43 Baby Clipper of VMJ-2 in San Diego. The military
version of this aircraft was designated the JRS-1. They were
designed as smaller airliners and military transport vehicles.
Fifty three were built, and only three survive today.

Beech 2000A Starship. It was one of the most technologically
advanced aircraft of its type. Burt Rutan designed this
aircraft in 1982. Despite it's advances, it was a commercial
failure. Of the 53 built only 2 or 3 are still being flown.

Sud Aviation SE-210 Caravelle. The Caravelle was the first
jetliner produced by a European company other than the UK. The
aircraft was the first to mount the engines on the rear
fuselage. It was introduced into airline service in 1959 and
the last flying Caravelle was retired in 2004.

Hawker-Siddeley FRG.1/XV-6A Kestrel. Joint testing with pilots
from the US, UK and West Germany in 1965 on this aircraft
showed promised for a VTOL aircraft. The US bought six
aircraft after the testing at RAF West Raynham. Ironically,
the US Military said it had no use for such an aircraft. A few
years later, the USMC began flying the AV-8 Harrier, a
descendant of the Kestrel.

Hawker-Siddeley FRG.1/XV-6A Kestrel. Closer examination of
what I thought was a Harrier revealed USAF markings. The USAF
never flew Harriers, so I knew this one was something
different.

Kestrel, which is currently under restoration.

Beech AT-11 Kansan in WWII USAAF colors. The AT-11 was used to
train bombardiers and aerial gunners. A Beech 18 was altered
with a plexiglass nose and Norden bombsight. A bomb bay was
also added to carry 1000 pounds of bombs. Guns were added to
the nose and top of the aircraft for gunnery training.

Culver PQ-14B Cadet. These aircraft were built from wood and
designed to be manned or flown by remote control to train
aerial gunners.

Ruhrstahl SD-1400 Fritz-X. The Fritz-X was a German
anti-shipping bomb that could be guided from it's drop
aircraft by radio control.

Nakajima Ki-43-IIB Hayabusa (Oscar) of the IJAF 63rd Sentai
based in New Guinea. The Oscar entered service in 1941and were
armed with just two machine guns in the nose throughout the
war.

Boeing YC-14. The YC-14 was designed to replace the C-130. It
competed against the McDonnell-Douglas YC-15. In the end, the
USAF bought the improved version of the C-130. This is one of
only two built.

Northrop YC-125A Raider. The C-125 was designed to be used for
tactical transport on unimproved fields. The Raider was the
last tri-engined aircraft built for the US Military. When they
entered production their primary jobs were being taken by
helicopters. Twenty-three were built, most of them going to
Latin America. Today, only 2 survive, both in museums in the
US.

Boeing NB-52A Stratofortress from the USAF Flight Test Center
at Edwards AFB. This is a rare aircraft as it was one of only
3 A models built, and this one was used to drop the X-15 for
testing.
