Randomized Controlled Trials of Parachute Intervention

Apparently, there are none. At minimum, the paper called Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomised controlled trials reported the following summary of their results in the preamble to their paper: "We were unable to identify any randomised controlled trials of parachute intervention."

The paper does have a serious undertone, however, as the authors are commenting about the limits of evidence-based medicine.
