The terminal velocity of somebody falling out of a plane at 30,000 feet is around 120 mph depending on how they orient themselves. Wind drag is the reason; in a vacuum, the subject would just keep getting faster until impact.
88 feet per second = 60 miles per hour. So 120 mph = 176 feet per second.
A round fired out of my .45 XD leaves the barrel at about 860 feet per second.
So somebody falling out of a plane is going slightly faster than 20% as fast as a bullet, at impact.
This has absolutely no significance, unless you just fell out of an airplane without a parachute.
