It seems to be a contrived joke: They tested people jumping with and without parachutes from a small airplane situated on the ground.

It's a follow-up to a previous article bemoaning the lack of a randomised controlled trial of parachutes and arguing that they should not therefore be accepted as a valid 'treatment' for falling out of an aeroplane (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC300808/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC300808/). Both this article and its predecessor were published in the Christmas issue of the BMJ, where funny papers with a semi-serious point (in these cases, the ongoing debates in medicine about the superiority of RCTs over other forms of clinical evidence) are common. My favourite of this genre is "Does Peppa Pig encourage inappropriate use of primary care resources?" (https://doi.org/10.1136/bmj.j5397 https://doi.org/10.1136/bmj.j5397) critiquing the clinical practice of Dr Brown Bear, a fictional cartoon GP.

  My favorite BMJ Christmas article is a study of self-reported virgin mothers [1], but I might be biased because I know one of the authors. [1] https://www.bmj.com/content/347/bmj.f7102 https://www.bmj.com/content/347/bmj.f7102

Randomized studies of new treatments often exclude the sickest patients that could have benefitet most from the treatment. In particular, there won't be any really seriously ill patients in the control group because they will most likely die without treatment. That skews the results of these studies. This is what they try to illustrate with the jumping out of plane study. The result won't be reliable if you don't have a control group that actually might have benefit from the treatment. Cancer patients (jumpers), will or will not get a new type of chemotherapy (parachute). But since it is known that the sickest (hightest jumping hight) certainly will die without treatment (parachute), they decide to only test the treatment on patients with only early stage and benign cancer (close to the ground).
