"When you push against a system and it is an unjust system, you must prepare yourself mentally for the isolation and resistance that comes with that. Activism and whistleblowing looks sexy on TV, but it’s hard on your mind and wellbeing." --Dr. Monica Cox greeneracresvaluenetwork.wordpress.com/2022/04/27/dai…

🧵: Have you heard the story of Charles “Bub” (or “Bud”) Cowart, the sailor who in May 1932 spent almost two hours dangling from a rope beneath the airship USS Akron before he was finally rescued? #AviationHistory
2/ It’s a wild story I discovered while researching my family’s history with airships. My great-great grandfather was director of the Goodyear-Zeppelin Corporation — here he is with the father of naval aviation, Admiral Moffett, who would die in the crash of the Akron in 1933.
3/ C.E. Rosendahl was in command of the Akron during the Cowart incident and recounts the story in his 1938 book “What About the Airship?” — which even then was “advocating a lost cause,” as the NY Times put it in a charitable review: timesmachine.nytimes.com/timesmachine/1…

On 7/18/74, @NASA bought a @Boeing 747-123 from @AmericanAir for ~$15.6 million. According to NASA, “At the time of purchase, the aircraft had logged about 9,000 flight hours.”

The red, white, & blue paint stripes from the @AmericanAir livery was even left in place. The NASA Worm logo was added on the tail. More historical pictures can be seen here:

Designed & tested at McCook field in 1948 by Heinrich and Gross: the highly-stable ribless guide-surface parachute. This chute was mass-produced mostly as stabilization chutes; but there was a version aimed at landing personnel as well. 1/5. @McCookField @AFmuseum @AFResearchLab
This design was deemed “stable”, I.e., less prone to swinging like a pendulum during descent or while decelerating payload. Per frame “e” below, it generates a stronger restoring moment whenever tilted. Figure from T. Knacke’s “Parachute recovery systems design manual”. 2/5.
Guide-surface chutes are still used today as ejection seat drogues. They are based on a gore pattern that is easier to sew together. Top right photo from Kididis’ “Art of Drag“. Harrier jet e-seat drogue pics by @LaboPotvin . 3/5
