Big Fans, Bigger Feelings
Historic Photos of NASA's Cavernous Wind Tunnels
These giant NASA tunnels blew minds—and sparked a serious "we can’t build like this now" spiral
TLDR: NASA’s historic photos showed off massive wind tunnels that helped shape aircraft research for decades, while also highlighting Mary Jackson’s path to becoming the agency’s first Black woman engineer. In the comments, people swung between amazement, jokes, and a surprisingly emotional debate over whether we still build anything this ambitious.
NASA dropped a set of jaw-dropping historical photos of its enormous old wind tunnels—the giant machines used to test aircraft by blasting air at them at extreme speeds—and the internet immediately turned the comment section into a mix of awe, nostalgia, and existential crisis. One standout image showed a technician inside the huge 16-foot tunnel at Langley in Virginia, a facility built in 1939 and retired in 2004. Another showed workers standing on top of a gigantic tunnel in the 1940s like they were casually hanging out on a steel mountain. And woven into the photo set was the story of Mary Jackson, who pushed past segregation-era barriers to become NASA’s first Black woman engineer.
But let’s be honest: the real turbulence was in the replies. One commenter basically looked at the massive structures and said modern society feels like a fallen empire staring at ancient wonders, comparing these projects to Roman aqueducts and wondering if we still build anything this bold. That mood got a lot of traction. Others zoomed in on the famous 1937 construction shot with horses, calling it the perfect “old world meets future tech” image. Then came the classic internet hot take: everybody starts by copying. A commenter pointed out that America’s first wind tunnel was modeled after a British one, turning the thread into a mini life lesson about how innovation often starts with imitation. And of course, Formula 1 fans arrived right on cue, fantasizing about what race-car design legend Adrian Newey could’ve cooked up in one of these monster tunnels. History, inspiration, insecurity, memes—this thread had lift.
Key Points
- •NASA Langley’s 16-foot transonic wind tunnel was built in 1939, operated until 2004, and was later retired under a national wind-tunnel optimization initiative.
- •The transonic tunnel moved air through its test section at approximately 150 to 1,000 miles per hour, spanning speeds across the sound barrier.
- •Its guide vanes formed an ellipse 58 feet high and 82 feet wide, with vane sets at four corners directing airflow through a 1,000-foot enclosed loop.
- •The article also features the NACA altitude wind tunnel circa 1945, a large rectangular structure with legs measuring 263 feet and 121 feet, and a west end 51 feet in diameter.
- •Mary Jackson began at NACA Langley in 1951, trained through graduate-level coursework and wind-tunnel work, and became NASA’s first Black female engineer in 1958.
