Cool High Precision Engineering pictures

A handful of nice higher precision engineering photos I found:

Quoting Smithsonian National Air and Space Museum | Vought OS2U-3 Kingfisher:

The Kingfisher was the U.S. Navy’s main ship-primarily based, scout and observation aircraft for the duration of World War II. Revolutionary spot welding strategies gave it a smooth, non-buckling fuselage structure. Deflector plate flaps that hung from the wing’s trailing edge and spoiler-augmented ailerons functioned like additional flaps to permit slower landing speeds. Most OS2Us operated in the Pacific, where they rescued numerous downed airmen, like World War I ace Eddie Rickenbacker and the crew of his B-17 Flying Fortress.

In March 1942, this airplane was assigned to the battleship USS Indiana. It later underwent a six-month overhaul in California, returned to Pearl Harbor, and rejoined the Indiana in March 1944. Lt. j.g. Rollin M. Batten Jr. was awarded the Navy Cross for generating a daring rescue in this airplane below heavy enemy fire on July four, 1944.

Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress &quotEnola Gay&quot:

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Planet War II and the first bomber to property its crew in pressurized compartments. Though created to fight in the European theater, the B-29 discovered its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: traditional bombs, incendiary bombs, mines, and two nuclear weapons.

On August 6, 1945, this Martin-constructed B-29-45-MO dropped the very first atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum close to Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Wonderful Artiste, flew as an observation aircraft on both missions.
