💁🏻♀️ TIL: 🏰⚙️ #Aerospace engineer Tom Stanton built a backyard #trebuchet powerful enough to launch a projectile past the speed of #sound.
He redesigned the ancient siege weapon with a 3:1 pulley system and a longer sling that revolved multiple times to gain #momentum. After extensive trial and error, his release cracked the whip of a #sonicboom at 1,249 km/h (776 mph), just clearing the 1,234 km/h (767 mph) barrier.

The museum has one very famous civilian #Aeroplane and that is the first British #Concorde to be flight tested (in 1969 I think). It’s still the only #Supersonic civil aircraft to have gone into service. Here are its starboard #JetEngines.
