  1. You are all wrong. Take a look at this.

    On August 16th, 1960, as a part of the Air Force research program (Project Excelsior), Air Force Capt. Joseph W. Kittinger Jr. stepped off a platform raised to 102,800 feet over Tularosa, New Mexico by a high-altitude balloon.

    The Air Force program was designed to investigate the use of a parachute for escape from a space capsule or high-altitude aircraft. To survive the altitude Kittinger wore a pressure suit like those for astronauts.

    After 4 minutes, 36 seconds of free fall Kittinger reached a speed of 714 mph (becoming the only human to break the sound barrier without being enclosed in a machine of any kind) and falling 84,700 feet before opening his parachute. He landed safely after 13 minutes, 45 seconds after jumping.


  2. Not in an aircraft?  Okay, I'll be a smartass:

    The Apollo 10 crew; Thomas Stafford, John W. Young and Eugene Cernan achieved the highest speed relative to earth ever attained by humans at 24,790 mph.  The record was set May 26, 1969.

    Note that this happened in a SPACECRAFT.

  3. I thought it was 120mph, when Keeno Reeves jumped out of that areoplane in Point Break:, chasing whatshisname...Patrick Sleezy.

  4. The highest speed achieved by a human outside of any aircraft (or spacecraft :P) is 614 mph (988km/h). This speed was achieved by Joseph Kittinger in 1960 when he performed a free-fall jump from a balloon, exiting the balloon at 102,800 feet (31 333.44 meters).

  5. 9.8 meters per second squared STRAIGHT DOWN when the da vinci wings failed!

    Or, 1/2 mv^2 when the Great Gandini was shot from a cannon!

  6. Don't  know, how fast can you fall off a cliff?  ; )

  7. Terminal velocity for a human is between 100-120 mph, so if someone jumped off a high cliff, like at the Grand Canyon, that is the speed that they would reach.
