There has been air activity over #Belgorod, #Russia tonight (May 1-2). At first it seemed to be just air defense measures or perhaps an air battle (see below). But now there are reports of explosions that sound like more than just sonic booms. 🧵 for updates & clarifications. 1/
Thus far, there have been reports of two #explosions overnight in #Belgorod, #Russia, occurring during or after air activity also was visible. This video records one of the explosions. 2/
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

He won acclaims and appreciations from many.
After five years one day he was sitting with his wife in a restaurant. A man from another table came to him & said "You're Captain Vishal! You flew jet fighters. You were shot down!"
“How in the world did you know that?” asked Vishal

“I packed your parachute," the man smiled and replied.
Vishal gasped in surprise and gratitude and thought if parachute hadn't worked, I wouldn’t be here today. Vishal couldn't sleep that night, thinking about that man.
