K-7 Kalinin
Designation K-7 was originally assigned to project of 3-engined 22-seat transport (aka the K-Tjazholij, K-Heavy). When this project was abandoned, the K-7 became an experimental heavy bomber.
Basically it was an enormous, thick (mechanics were able to walk to engines during the flight), elliptical flying wing design, with twin tail booms, a nacell protruding from the leading edge, and six-wheeled landing gear - each three wheels enclosed in enormous fairings, that contained also 2 gunner positions each and the entrance stair. Defence were arranged so that any direction was covered by at least three gunners.
There was an option to carry a 8.4 tons tank (or other equipment to be parachuted) between the main gears and 112 paratroopers.
First test flights were successful, but later the single prototype crushed during maximum speed test. The cause of crash was infamous "flatter"... But it was little known about at the moment.

Northrop Tacit Blue 'The Whale'
U.S.A.F. Tacit Blue Stealth Demonstrator
The U.S. Air Force unveiled the Tacit Blue Technology Demonstration Program on 30 April 1996, at The Pentagon. Tacit Blue was created to demonstrate that a low observable surveillance aircraft with a low probability of intercept radar and other sensors could operate close to the forward line of battle with a high degree of survivability. Such an aircraft could continuously monitor the ground situation behind the battlefield and provide targeting information in real-time to a ground command center. Tacit Blue validated a number of innovative stealth technology advances.
Tacit Blue, nicknamed "the whale," featured a straight tapered wing with a Vee tail mounted on an oversized fuselage with a curved shape. A single flush inlet on the top of the fuselage provided air to two high-bypass turbofan engines. Tacit Blue employed a quadruply redundant, digital, fly-by-wire flight control system to help stabilize the aircraft about its longitudinal and directional axes.
The sensor technology developed for Tacit Blue is now being used by the E-8 Joint STARS aircraft
Operational history
The aircraft made its first flight in February 1982, and subsequently logged 135 flights over a three year period. The aircraft often flew three to four flights weekly and several times flew more than once a day. After reaching about 250 flight hours, the aircraft was placed in storage in 1985. In 1996, Tacit Blue was placed on display at the National Museum of the United States Air Force at Wright Patterson Air Force Base, near Dayton, Ohio. In February 2006 Tacit Blue was moved to one of the Museum's restoration hangars where it now awaits restoration next to Memphis Belle, the first B-17 to complete 25 missions in WWII. As of mid-September 2006, Tacit Blue is on display in the Presidential Hangar (within the Wright-Patterson Air Force Base perimeter and away from the main National Museum site).

Armstrong Whitworth AW52
The Armstrong Whitworth A.W 52 was an elegant
aircraft, designed expressly as a research machine for
determining the flying characteristics of large tailless
aircraft and to provide data for a projected six-jet high
speed transport of generally similar configuration.
The first prototype A.W. 52 flew on November 13 1947,
powered by two 5000lb thrust Rolls Royce Nene
turbojets. A second prototype, powered by two 2,500lb
Rolls Royce Derwent units followed on September 1, 1948,
but the latter aircraft was destroyed early in its
flight programme.
The outboard wing sections were swept at an angle of
35 degrees at the leading edge, and longitudinal and
lateral control was by means of elevons hinged on each
outer wing section. Directional control in yaw was by
means of wingtip rudders.
The Nene powered first prototype A.W 52 completed a
prolonged research programme and was certainly one of
the most graceful aircraft of its time.

Flash Gordon's speeltje?
Klopt niet helemaal... het relief van de romp achter de cockpitruiten is anders. Ook is het achtereinde van die cockpitruiten op Prop-ers foto spitser dan op de eerste foto.
Er zijn dus minstens twee versies van geweest...
In elk geval kan je hier zien dat-ie Frans is...
