The Vought XF5U "Flying Flapjack" was an experimental U.S. Navy fighter aircraft designed by Charles H. Zimmerman during World War II. This unorthodox design consisted of a flat, somewhat disc-shaped body (hence its name) serving as the lifting surface.[SUP][1][/SUP] Two piston engines buried in the body drove propellers located on the leading edge at the wingtips.
[h=2]Design and development[edit][/h]A developed version of the original V-173 prototype, the XF5U-1 was a larger aircraft. Of all-metal construction, it was almost five times heavier, with two 1,600 hp (1,193 kW) Pratt & Whitney R-2000 radial engines. The configuration was designed to create a low aspect ratio aircraft with low takeoff and landing speeds but high top speed.[SUP][2][/SUP]
Normally, a wing with such a low aspect ratio will suffer from very poor performance due to the degree of induced drag created at the wingtips, as the higher pressure air below spills around the wingtip to the lower-pressure region above. In a conventional aircraft, these wingtip vortices carry a lot of energy with them and hence create drag. The usual approach to reducing these vortices is to build a wing with a high aspect ratio, i.e. one that is long and narrow. However, such wings compromise the maneuverability and roll rate of the aircraft, or present a structural challenge in building them stiff enough. The XF5U attempted to overcome the tip vortex problem using the propellers to actively cancel the drag-causing tip vortices.[SUP][3][/SUP] The propellers are arranged to rotate in the opposite direction to the tip vortices, with the aim of retaining the higher-pressure air below the wing. With this source of drag eliminated, the aircraft would fly with a much smaller wing area, and the small wing would yield high maneuverability with greater structural strength.
The propellers envisioned for the completed fighter — unlike the torque-reducing counter-rotating propellers of the V-173 design — were to have a built-in cyclic movement like a helicopter's main rotor, with a very limited ability to tilt up and down to aid the aircraft in maneuvering. An ejection seat was fitted to allow the pilot to clear the massive propellers in the event of an in-flight emergency.[SUP][2][/SUP] Although the prototype was unarmed, a combination of machine guns and cannons would have been installed under the nose.[SUP][2][/SUP]
[h=2]Testing and evaluation[edit][/h]The XF5U design was promising: specifications given at the time promised great maneuverability and speeds up to 550 mph (885 km/h).[SUP][4][/SUP] However, it came at the time when the United States Navy was switching from propeller driven to jet propelled aircraft. By 1946, the XF5U-1 project was already long over its expected development time, and well over budget.[SUP][2][/SUP] With jet aircraft coming into service, the Navy finally canceled the project on 17 March 1947, and the prototype aircraft (V-173) was transferred to the Smithsonian Museum for display. Although two aircraft were constructed, a lone XF5U-1 underwent ground runs but never overcame vibration problems. Taxi trials at Vought's Connecticut factory culminated in short "hops" that were not true flights.[SUP][5][/SUP][SUP][6][/SUP] The only completed XF5U-1 proved to be so structurally solid that it had to be destroyed with a wrecking ball.[SUP][7][/SUP]

The remaining B-58's were retired in 1970, much to the relief of their surviving crews. It's accident record was atrocious. Performance was remarkable for it's time, though.

Now that's what I call Hustle! RCGuy you're up
Convair B-58 Hustler
https://en.wikipedia.org/wiki/Convair_B-58_Hustler
What warbird am I looking for?
1)Introduction into active service was on the “ides of March,1960
2)Crewed by three
3)While its performance and design were exceptional and appreciated, it was never easy to fly
4)The Primary user was the same country that developed it
5)Four Engine jet
6)One of the first extensive applications of aluminum honeycomb panels
7)Defensive armament consisted of a single 20 mm rotary cannonwith 1,200 rounds of ammunition in a radar-aimed tail barbette
8)Later versions gave each crew member a novel ejection capsule
9)It was only in service for a little over ten years
10)Turn and burn speed of Mach 2.0 (1,319mph) at 40,000 ft.(12,000 m)

Looking for the name of a warbird pilot.
1. He became interested in aviation while in grade school.
2. As a kid, he was an avid modeler, mostly free-flight and control line.
3. He began flying full-size aircraft as a teenager and received his military pilot's wings by the age of twenty.
4. He flew over 200 different aircraft in his flying career and was forced to eject twice, once in combat.
5. His most famous mission occurred during the Vietnam War.

Looking for a pilot.
1. A very high-scoring fighter pilot.
2. Though he got off to a slow start. During his first year in combat he was shot down and had no victories himself.
