Abstract
Objective To determine if using a parachute prevents death or major traumatic injury when jumping from an aircraft.
Design Randomized controlled trial.
Setting Private or commercial aircraft between September 2017 and August 2018.
Participants 92 aircraft passengers aged 18 and over were screened for participation. 23 agreed to be enrolled and were randomized.
Intervention Jumping from an aircraft (airplane or helicopter) with a parachute versus an empty backpack (unblinded).
Main outcome measures Composite of death or major traumatic injury (defined by an Injury Severity Score over 15) upon impact with the ground measured immediately after landing.
Results Parachute use did not significantly reduce death or major injury (0% for parachute v 0% for control; P>0.9). This finding was consistent across multiple subgroups. Compared with individuals screened but not enrolled, participants included in the study were on aircraft at significantly lower altitude (mean of 0.6 m for participants v mean of 9146 m for non-participants; P<0.001) and lower velocity (mean of 0 km/h v mean of 800 km/h; P<0.001).
Conclusions Parachute use did not reduce death or major traumatic injury when jumping from aircraft in the first randomized evaluation of this intervention. However, the trial was only able to enroll participants on small stationary aircraft on the ground, suggesting cautious extrapolation to high altitude jumps. When beliefs regarding the effectiveness of an intervention exist in the community, randomized trials might selectively enroll individuals with a lower perceived likelihood of benefit, thus diminishing the applicability of the results to clinical practice.

Democrats now concerned that vile, unconstitutional behavior, rampant lies, insincere campaign promises, blaming opponents for their own failures, and captured propaganda MSM will be insufficient to help them cheat their way to victory in the midterms
@richwicks After you mentioned Charles de Gaulle sending a warship to pick up France's gold from America, I read a bit about him.
Aside from that act of audacity, I liked that he quickly learned to hate all politicians after becoming leader of France. He was convinced they were all just out for themselves, which sounds correct. Then he quit. He got drawn back into being leader of France later, but never changed his views.
Ho Chi Minh took them up on the offer, and the Allies didn't hold up the bargain in the end.
Remember, you can't patent a naturally occurring pathogen:

I actually admire DeGaulle, he was a nationalist. He told the first President of the proto-EU European Commission to F Off. He was "France First".
