It's about 4,000 times as fast as a Helicopter.
In other words, 955 mach is 4,010 times the speed of a Helicopter, and the speed of a Helicopter is 0.000249 times that amount.(for AH-64A Apache, a.k.a. Hughes Model 77) (maximum cruise speed)
The AH-64 helicopter, one of the primary helicopters used by the United States Army, flies at a top cruise speed of 0.2380 mach. The AH-64 is the primary military helicopter of several nations including the United States, the United Kingdom, Israel, Japan, and the Netherlands.
It's about 4,500 times as fast as a Skydiver (headfirst).
In other words, the speed of a Skydiver (headfirst) is 0.00023 times 955 mach.(Head-to-Earth orientation or standing, average conditions, terminal velocity)
A head-to-Earth or standing-oriented skydiver's terminal velocity assuming average conditions is about 0.220 mach. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 46 seconds.
It's about 5,500 times as fast as a Tornado.
In other words, 955 mach is 5,735.1320 times the speed of a Tornado, and the speed of a Tornado is 0.0001743639 times that amount.(EF2) (wind speed range average)
According to the Enhanced Fujita scale implemented by the US National Oceanographic and Atmospheric Administration, a "significant" tornado has an Enhanced Funjita scale classification of EF2 and is characterized by wind gust speeds between 0.14831520 mach and 0.18471980 mach. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
It's about 6,000 times as fast as a Skydiver (belly-to-earth).
In other words, the speed of a Skydiver (belly-to-earth) is 0.00017 times 955 mach.(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 0.160 mach. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 60 seconds.
It's about 7,500 times as fast as a Fastball (baseball).
In other words, the speed of a Fastball (baseball) is 0.00013 times 955 mach.(a.k.a. rising fastball, a.k.a. cross-seam fastball, a.k.a. heater, a.k.a. hummer, a.k.a. smoker; for four-seam grip) (major league average)
The average speed of major league fastball pitch is 0.130 mach. When up against the quickest professional fastball pitchers, a batter may have less than 0.4 seconds to react to a pitched ball.
It's about 9,500 times as fast as a Curveball (baseball).
In other words, the speed of a Curveball (baseball) is 0.00011 times 955 mach.(a.k.a. hook, a.k.a. hammer, a.k.a. yakker) (major league average)
The average speed of major league curveball pitch is 0.10 mach. In the 1940's, debate over whether there really was a curve in the curveball pitch was settled with the conclusion that the ball does curve; however, an optical illusion caused by the spin of the ball and the batter's perception of motion exaggerates the extent of the curve.
It's about 9,500 times as fast as a Hurricane.
In other words, 955 mach is 9,570 times the speed of a Hurricane, and the speed of a Hurricane is 0.000104 times that amount.(formally: Topical cyclone; a.k.a. typhoon)
A hurricane is defined by the US National Hurricane Center as a Northern Hemisphere tropical storm having one-minute average wind-speeds of at least 0.0997 mach. Typhoons Tip (October, 1979) and Keith (October, 1997) and Hurricanes Camille (August, 1969) and Allen (August, 1980) jointly hold the record for highest tropical storm wind speeds at 0.260 mach.
