In 1946, NACA (NASA) wanted to see how much wind a human could tolerate. Specifically, they sought "to obtain direct evidence of the forces involved when the human head is suddenly thrust into a rapidly moving air stream."
This became important when ejection seats started to standardize. Blasting someone out of a canopy into the jet stream warranted a little looking into.

Thread: The weird story of how a carefully covered up German air raid in WW2 contributed to the development of modern chemotherapy drugs.
As the tide of WW2 turned in late 1943, the allies suspected that increasingly desperate Germans would turn to chemical weapons. In preparation, they secretly parked a boat load of mustard gas at the captured Italian port of Bari.
On the night of December 2, 1943, 105x Ju-88 bombers hit the harbor at Bari hard, sinking or damaging 40 allied ships.

Beginning in 1967, the Soviet Union placed a series of radar-equipped ocean reconnaissance satellites (RORSATs) in orbit. In order to return useful data, they had to fly quite low...so low that using solar panels would have caused drag that decayed their orbits very quickly.
To save weight, lower drag, and increase usable lifespan, Soviet engineers opted for BES-5 nuclear reactors fueled by uranium-235. They provided 2KW of power per satellite.
But, yeah, putting highly radioactive material in very low earth orbit? Not a great idea.

You can imagine what happened next.

It's not from the 70s.
Or the 60s.
Or even the 1950s.

Feast your eyes on the Northrop YB-49 Flying Wing...circa 𝟭𝟵𝟰𝟳.
The YB-49 began life as the YB-35: A piston powered heavy bomber prototype. They were designed as a contingent in the event that England fell to the Nazis. They were to carry crew of 9 over 8,000 miles with up to 50,000lbs of bombs.
At the end of the war, the YB-35 got upgraded from pistons to jets, gaining 8x Allison J35-A-15 turbojets and a new designation: YB-49.

In the early hours of September 3, 1916, bombs joined the rain falling from the sky above London Colney and South Mimms, England.
Obscured by might, the crew of Zeppelin Schütte-Lanz SL 11 dropped their high explosive payload. Shortly after, they were picked up by searchlight above Hornsey and targeted by an ineffective barrage. They slipped into the clouds undamaged.
Roughly 15 minutes later, the monolithic SL 11 began bombing Ponders End. The ship was spotted again by searchlights at Waltham Abbey. This time, fighters scrambled into action.

Spacelab was a modular laboratory flown in the cargo bay of the Space Shuttle.
1-connecting tunnel between orbiter and Spacelab.
2-payload space hinges
3-footstalks
4-experimental unit
5-hyperbaric modules
6-external platform
7-infrared telescope
8-magnetic field probe
9-payload space
10-back side of front part of orbiter
There are not a lot of images of the connecting tunnel, which ran the length of the cargo bay. It was one of the most exposed places an astronaut could be on a shuttle mission.
