on July 11th in 1953, Major John Bolt became the first USMC jet ace of the Korean War while flying an F-86 Sabre.  He was an exchange pilot with the USAF during his air victories. He served under the leadership of triple ace Captain Joseph McConnell.
His total of 6 confirmed victories were against Mig-15's.  He was also an ace in WWII flying with VMF-214 Blacksheep in F4U Corsairs and was credited with 6 victories over Japanese Zeros. 
When he passed away in 2004, he was the last of the seven pilots who were dual aces in WWII and Korea.

Yup, they tested the Nagasaki design as they weren't sure it would work.  The Hiroshima type was never tested before use, it was a simpler device.

It's pretty amazing they developed two very different atomic bombs at the same time, in effect, using two parallel approaches.  One required generation of a new element, plutonium.  There was some serious brain power afoot there.

Cyclorama: The Big Picture | Exhibitions | Atlanta History Center

On February 22, 2019, Atlanta History Center opened Cyclorama: The Big Picture, featuring the fully restored cyclorama painting, The Battle of Atlanta.

At the centerpiece of this new multi-media experience is a 132-year-old hand-painted work of art that stands 49 feet tall, is longer than a football field, and weighs 10,000 pounds. This painting is one of only two cycloramas in the United States—the other being the Battle of Gettysburg cyclorama —making Atlanta home to one of America’s largest historic treasures.

77 years ago this morning the very first atomic device explosion was conducted as a test in the New Mexico desert.

Sure that wasn't Keggs and Eggs in C-Bus?

It is a reflection of the United State's dominant economic position. 

The US was approximately 50% of the world's industrial capacity. The US was able to build the world's largest navy. By the end of the war the US Navy was literally more powerful than all other navies in the world combined. 

Seriously, think about that. In 1945 if every warship in the world had met somewhere for a gigantic everyone vs US battle, the US would have won. Beyond that, the US would have won by default because only the US had the logistical capacity to fuel and supply a fleet literally anywhere in the world. 

The US also produced astounding quantities of tanks, trucks, supply ships, aircraft, etc.

What makes this even more amazing is that while doing all of the above the US had enough surplus capacity to successfully complete the Manhattan Project at the same time.
