The Boeing B-29 Superfortress makes its maiden flight.
The Boeing B-29 Superfortress made its first flight, ushering in a new era of long-range bombing.
On September 21, 1942, the Boeing B-29 Superfortress, then the most advanced heavy bomber in development, took to the skies for the first time.
Equipped with state-of-the-art features such as a pressurized cabin and remote-controlled gun turrets, it represented a leap in aerial warfare technology.
The B-29 would eventually play a crucial role in the Pacific Theater, including the missions that ended World War II.
Its maiden flight tested engine performance, flight controls, and structural integrity at high altitudes.
The success of this inaugural mission validated Boeing’s ambitious design and paved the way for full-scale production.
Today, the B-29 is remembered as an iconic aircraft that reshaped strategic bombing doctrine.

The North American XB-70 Valkyrie, the world's fastest bomber, makes its maiden flight from Palmdale, California.
The XB-70 Valkyrie, the world’s fastest bomber prototype, completed its maiden flight from Palmdale.
On September 21, 1964, North American’s XB-70 Valkyrie soared into the skies above Palmdale, California for its first flight.
Designed to cruise at Mach 3 at high altitude, the Valkyrie featured a sleek delta wing and six powerful engines.
The prototype program aimed to develop a strategic bomber capable of penetrating Soviet airspace during the Cold War.
Although promising, the project was eventually canceled due to advances in surface-to-air missile technology.
The two surviving prototypes are preserved in museums, showcasing cutting-edge aerospace engineering.
The XB-70 remains a symbol of Cold War ambition and innovation in aviation history.

The Galileo spacecraft is terminated by sending it into Jupiter's atmosphere.
NASA's Galileo mission ended when the spacecraft was deliberately sent into Jupiter’s atmosphere in 2003.
NASA's Galileo spacecraft met its end on September 21, 2003, as it was deliberately guided into Jupiter's atmosphere. Launched in 1989, Galileo provided unprecedented views of the giant planet and its moons. The mission confirmed subsurface oceans on Europa and volcanic activity on Io. Scientists chose the dramatic conclusion to avoid potential contamination of Europa's icy surface. During its final minutes, Galileo transmitted valuable scientific data back to Earth. The spacecraft disintegrated under Jupiter's intense pressure and heat, ending a storied mission that revolutionized planetary exploration.
