Researching how a human can survive a fall from very high hights

Researching this with a crash test dummy.

Legs down
-Normal and legs down
-Maybe head positions, normal and sideways for example
-Arms in front of the head, while keeping the head sideways
-Hands in front of the head, while keeping the head sideways

Landing sideways
-Just landing sideways
-Landing sideways while putting both hands at the head at the falling side
-Landing sideways while keeping one arm stretched out at the falling side

Landing horizontally, front of the body facing towards the ground:
-Just landing horizontally
-Landing horizontally while keeping the head sideways
-Landing horizontally with hands in front of the head, while keeping the head sideways
-Landing horizontally while stretching out the legs and arms
-Landing horizontally with outstretched legs and hands in front of the head while keeping the head sideways

Landing horizontally, back of the body facing towards the ground:
-With arms quiet a lot backwards maybe while scapula's are towards each other and head sideways
 -With hands behind the head

Landing on the knees in a sitting position
-Landing on the knees in a sitting position while protecting the head with the hands
-Landing on the knees in a sitting position while protecting the head with the arms

One problem: It's not possible to change the position of landing. Some test results might need to be put together, using calculations to make it as accurate as possible.
Example: Going down horizontally with outstretched arms and legs (The speeds are important with this one) and then going to a legs down position while protecting the head, while keeping the head in a certain position, for the hitting the ground part (for this part you need to calculate how much force would have been created on landing with the speed of the going down horizontally with outstretched arms and legs).

Extra: Seeing if something can be done with clothing to create drag.

Real life testing while falling on a very safe, soft air filled design, while wearing sensors.

And testing all this on different kinds of surfaces, from concrete to grass to sand and even water.

Extra:
1 Researching how a cat survives a fall from high hights (by ethical means, soft landing etc)
   -How it keeps it back and front legs
   -Very important: How it keeps it head
2 Researching how racoons fall and survive extreme falls
Extra: Maybe with sensors on the cat that measure heartbeat, respiration, angles of legs etc. 
Extra: Slow motion analysis
Extta: Analysing real existing footage. And also in slow motion.
