In a freefall, if the chute refuses to deploy properly, the
freefaller will be sent spiraling down the sky due to the pre
matured deployment of the faulty chute.
Centrifugal force coupled with terminal velocity will spin the
blood and bodily fluids into the ends of the body (head and toes)..
causing extreme G force on the brain and paralysis of the body.
In 10 seconds, even an experienced freefaller can get knocked
out cold if he/she doesnt eject the faulty chute to end the spiral
and to deloy his/her second chute.
Free falling is more risky as compared to normal static line
jumps.
My condolences...

i assume he blacked out before he could cut away and deploy his
reserve. Pity he is 1 or 2 yrs away from retirement. Hell of a way
to go. RIP
