The main advantage seems to be a lower descent rate of 12 feet/second, vs
the standard round emergency parachutes that have 18 feet/second. My high
school physics says it's about the difference between jumping off a 2.5
foot high ladder vs a 5 foot high ladder.


I _assume_ a better comparison would be jumping off a stationary 5 foot
ladder vs. jumping off a moving pickup truck?
