According to a 2018 randomized controlled trial published in The BMJ, parachutes are no more effective than backpacks at preventing death or major injury when jumping from an aircraft. The study involved 23 people who were randomly given either a parachute or a backpack and then jumped from a biplane or helicopter. The researchers found no statistically significant difference in the primary outcome (death)
between the treatment (parachute) and control (no parachute) arms.
