Falling with no restraints or aids.

No, elevators are equipped with safety mechanisms that prevent them from freefalling. These safety features include brakes, counterweights, and speed governors that engage in the event of a malfunction to stop the elevator from falling uncontrollably.
Acceleration is change in velocity. So it depends on both velocity and time.
The approximate acceleration of a body in freefall near the earths surface due to earths gravitational pull. The object in freefall gains 9.81 meters per second for every second that elapses (ignoring air resistance).
In orbit, astronauts appear weightless and float because they are in a state of constant freefall towards Earth. Due to the lack of air resistance and the gravitational pull being the only force acting on them, they experience the sensation of weightlessness.
Some words that contain the word 'free' are freedom, freely, freefall, and freeman.
Just as a leaf falls slower to the ground than a tennis ball, a skydiver changes his/ her body position to change the amount of surface area that is affected by air resistance. A flatter body position, for example, will slow a skydiver's freefall rate from a normal arched position.
They actually can breathe, though it is not "normal" because the air is rushing past them so fast. I never thought about my breathing when I was in freefall.
If you have never made a freefall parachute jump, start by getting some training at a local drop zone. In order to do base jumps with a wing suit it is recommended that you have advanced freefall skills. Without these skills you increase the risk of injury or death due to unstable deployment, contacted the wall of the cliff, or misjudging the distance to the ground.
Math: d=rt r=rate & t=time Physics: d=0.5gt2 (Freefall) g=acceleration due to gravity & t=time
US President, Bush senior has skydived in the 1990's. He made a war time parachute jump (but not a freefall skydive) in the 1940's in addition.
The fastest animal on earth is the Peregrine falcon in a hunting dive. They have been clocked at over 200mph during such stoops. This is probably the bird's terminal velocity -- perfect freefall.
