Baseball

I simply don't believe that number.
Clearly he was the fastest of his time but 107 is not credible.
The way he got the number is also questionable math. Plus, I simply don't believe the 117 mph starting value.
Wind resistance against a rotating sphere of that size doesn't decelerate the ball 19mph in 0.4 seconds. My calculations suggest it would approach 19mph with laminar aur flow. But, sheer velocity t takes the fluid characteristics out of laminar state, and the ball us spinning at over 2,000rpm with raised seems. U value estimates to 2 or 3 thousand.
There is insufficient mass of air.
Was he incredibly fast? You bet.
But, with the bat weights of hitters not doing weight training in those days, nobody ever would have caught up to a 107mph fastball.
Most guys in MLB today can't and they're using bats 3 to 5 ounces lighter & they all weight train year round.
This feels like YouTube click bait.
Not credible.
