About 55 meters per second is "terminal velocity". http://hypertextbook.com/facts/JianHuang.shtml
9.8 meters per second squared. So the longer they are in the air, they will fall faster by each second.
It will fall just as fast as an object of any other mass - assuming that air resistance is negligible. That is to say, if an object has a lot of surface area, it will fall slower due to air resistance.
Air resistance is basically friction between the object on the air- it has to push the air out of the way, and slows down.
if a plane stopped in mid air it would just fall and probely not because it would be going to fast for it to fast to just stop!

The Navy said around 1,500 mph, but I would bet on higher than that.
It is dangerous to jump from a fast moving train because you can get killed. You can also get hurt as well. You may jump off the train and land the wrong way and break something or become severely injured.
All objects fall at a rate of 9.8 meters per second, or, 23 miles per hour. However, this is how fast they would fall in a vacuum, which is hardly ever the case on earth. To find out their true speed, you would have to minus the air resistance as well.
You can't fall in space, there is no gravity. An object will travel as fast as it is accelerated and continue at that speed forever as there is no air resistence to slow it down.
Air pressure. For instance, in a complete vacuum, a feather would fall as fast as a lump of lead.
Fast air. Really, really fast air.
if there is no air then both will take same time.But due to presence of air person who is without parachute will take less time.
