The SSK estimates that 1 out of every 20,000 to 75,000 jumps result in death, which is estimate to be 1 in every 100,000 jumps. It is estimated parachutes to malfunction once in each 333 activations.
Twisted risers
Indeed why? There are videos of examples where a parachutist has deliberately set fire to their parachute in flight, however this is part of a stunt. For 99.9999999% of skydivers, they do not set fire to their parachute as it is needed to save their life. For your information, all skydivers wear a reserve parachute for use in the case of a malfunction of the main parachute.
It does not 'keep you in the air' a parachute slows down your rate of descent by traping air under the canopy.
mid air collision, parachute not opening, double malfunction on both main and reserve parachutes; that's some of them
wouldn't the air trapped in the parachute quickly go out, then you will quickly fall until splat on the ground
Drag. It reduced the fall rate to a survivable speed.
If the parachute is too small, then the load it is carrying will fall faster, the same thing is with big parachutes. If it is medium sized it will fall at a desirable rate than a larger or smaller parachute.
A parachute requires air (or an atmosphere) to work. So the parachute would be useless and fall at the same rate as you. Depending on your height, you would probably sustain severe injury and die.
Velocity x falling speed + the size of your junk
The decent rate will be significantly high on an open parachute because a 100 square foot parachute is considered to be very small. Therefore the wing loading is high and it is more likely to be a high performance parachute. High performance parachutes have a higher angle of attack and generally need to do a swoop (dive) landing to pick up enough wing speed for a safe landing. On touch down, the decent rate is the same as any other parachute for obvious reasons.
35 feet i think

There are several different types of malfunctions possible on a parachute while it is deploying. Everybody jumps with a spare parachute, known as a reserve. The parachutist identifies the type of malfunction and either cuts away the main parachute and deploys the reserve or if a cutaway isn't necessary just deploys the reserve straight away. Please note that cut away doesn't mean you have to cut all the lines with a knife, there is a pad that you grab and pull down which releases the main parachute.
