Terminal velocity is the maximum speed attainable by an object as it falls through a fluid ... face down) free fall position is about 55 m/s (180 ft/s). [3]
The speed, achieved by the human body in free fall, is a function of several factors; including the body's mass, orientation, and skin area and texture. [1] In stable, belly-to-earth position, terminal velocity is about 200 km/h (120 mph). Stable freefall head down position has a terminal speed of 240–290 km/h (around 150–180 mph).
A typical skydiver in a spread-eagle position will reach terminal velocity after about 12 seconds, during which time they will have fallen around 450 m (1,500 ft). [4] Free fall was demonstrated on the Moon by astronaut David Scott on August 2, 1971. He simultaneously released a hammer and a feather from the same height above the Moon's surface.
This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the terminal velocity is approached. In this example, a speed of 50 % of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90 %, 15 seconds to ...
A recreational wind tunnel enables human beings to experience the sensation of flight without planes or parachutes, through the force of wind being generated vertically. Air moves upwards at approximately 195 km/h (120 mph or 55 m/s), the terminal velocity of a falling human body belly-downwards. A vertical wind tunnel is frequently called ...

Interestingly, this was true for healthy adults but not people at high risk of developing cardiovascular disease. Other studies support the anti-inflammatory benefits of red wine consumption.
