Study 'Proves' Parachutes Don't Save People Who Fall Out of Airplanes.

▼ You might think that it's safer to jump out of an airplane with a parachute than without  one. But, according to science, you'd be wrong.
The finding is detailed Thursday (Dec. 13) in the journal The BMJ's Christmas issue, which features research that is more lighthearted than the journal's usual fare. For the study, the researchers tested the effectiveness of parachutes on 23 people falling out of airplanes. They equipped half of the participants with parachutes, and had the other half jump out of the planes with empty North Face backpacks strapped to their backs.They found that the parachutes made no difference on whether the participants in the study lived or died.
"Our groundbreaking study found no statistically significant difference in the primary outcome [death] between the treatment [parachute] and control [no parachute] arms," the researchers wrote. "Our findings should give momentary pause to experts who advocate for routine use of parachutes for jumps from aircraft in recreational or military settings."
Of course, it's hard to find people willing to jump out of airplanes thousands of feet in the airor moving hundreds of miles per hour, so they tested parachutes on people falling just a couple of feet toward the ground when the airplane was parked and not moving at all. (The researchers call this a "minor caveat" in the study design.)
But you have to read all the way down to the fourth paragraph of the study's report to figure that out. And, similarly, the researchers don't clarify until a good chunk of the way through their paper that the airplanes weren't actually flying, and that there was no change in the death rate because no one died in either group.

Haha. The caveat says this is out of a plane which is not moving and is stationary.
