The radical Douglas X-3 Stiletto was built primarily of titanium, and was intended to test high speed flight and low-aspect ratio wing design. Initial requirements indicated the aircraft would carry... More > the J-46 engine and be
capable of reaching cruising speeds above Mach 2.0. Problems with the J-46 engine, led Douglas engineers to substitute underpowered J-34 turbojets. Although the plane once achieved Mach
1.2 in a dive, it never went supersonic in level flight. Nevertheless, the plane was a valuable research tool and produced critical data about inertial coupling. The X-3 first flew in 1952
and was retired in 1956. Originally printed by the U.S. Air Force and NACA (later NASA), this hand-
book provides a fascinating glimpse inside the cockpit of one of history’s great planes. Classified “Restricted”, the manual was declassified and is here reprinted in book form. Although slightly reformatted, care has been taken to preserve the integrity of the text.< Less

In the late 1940’s and early 50’s, planes flew
higher and faster than anyone had dreamed
possible. The jet age had arrived, and along
with it came turbojet and rocket-powered
aircraft... More > capable of flying beyond the speed
of sound. To assess these aircraft, the Air
Research and Development Command
developed a series of data reduction methods,
and then compiled them in this Flight Test
Engineering Manual. It served as a standard
technical reference for the flight test
engineers, program managers, pilots and
support teams for many of the X-plane
programs of the 1950s. This reprint represents the first time in over fifty years that this book has been available, and the first time it has ever been made available to the public. it’s a unique time capsule that provides insight into the era
of “The Right Stuff”, when slide rules and
punch cards were the cutting edge, and a must-have for anyone interested in the technical aspects of flight test.< Less
Chance-Vought’s F7U Cutlass was inspired by design data retrieved from Germany’s Arado Company at the end of WWII. To avoid extreme nose-down forces, the Cutlass was a... More > “tail-less” aircraft. Its swept wings had vertical fins and “ailevator” control surfaces. Although intended to operate at up to Mach .95, the aircraft was hampered by under- powered Westinghouse turbojets, and its nose-up profile made carrier landings dangerous. Although its in-flight performance was acceptable, the Navy initially rejected the plane as unfit for carrier use. While nearly 200 F7U-3s were eventually delivered, they were retired only five years after their introduction. Originally printed by the U.S. Navy, this F7U-3 Flight Operating Manual taught pilots everything they needed to know before entering the cockpit. Classified “Restricted”, it was recently de- classified and is here reprinted in book form. This facsimile has been reformatted.

Designed without horizontal stabilizers, the X-4 Bantam had a semi-tailless design that bore some resemblance to Germany’s Me-163 rocket plane. The small, twin-jet craft relied on combined... More > elevator and aileron surfaces — known as elevons — for pitch and roll control. The role of the X-4 was to explore the transonic speed zone, and to determine whether the design would lessen the stability and control problems affiliated with compressibility. Although two Bantams were built, only one proved mechanically sound. The second was flown over eighty times by Northrop, Air Force and NACA pilots. They learned that the X-4 was sensitive in pitch, and showed a tendency to “hunt” about all three axes as it approached Mach 1.0. Thus, the X-4’s design proved a failure. Originally printed by Northrop, NACA and the USAF, this handbook provides a fascinating glimpse inside the cockpit of this experimental plane.
