Discussion Overview

The discussion revolves around the claim that a backpack is as effective as a parachute when jumping from a plane, based on a study that critiques scientific methods and the importance of context in research. Participants explore the implications of this claim, its humor, and the nuances of parachuting safety.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants reference a study suggesting that parachutes do not provide more protection than an empty backpack, emphasizing the study's focus on scientific methodology rather than practical safety.
  • One participant shares a humorous anecdote about a scenario involving dignitaries and parachutes, suggesting that training and knowledge about parachuting are crucial for safety.
  • Another participant draws a parallel to a different study claiming that listening to a specific song makes one younger, highlighting the absurdity of certain research conclusions.
  • Concerns are raised about the hypothetical scenario of the hippie and boy scout, questioning whether they would know how to safely glide or land using a parachute.

Areas of Agreement / Disagreement

Participants express skepticism about the study's conclusions, with some finding humor in the situation. However, there is no consensus on the implications of the study or the effectiveness of parachutes versus backpacks.

Contextual Notes

The discussion highlights the importance of context in interpreting research findings, particularly regarding the conditions under which the study was conducted, such as the height of the jump being less than 1 meter and the aircraft being stationary.

Is a backpack as good as a parachute when jumping out of a plane?

"Research published in a major medical journal concludes that a parachute is no more effective than an empty backpack at protecting you from harm if you have to jump from an aircraft."

If you're skeptical, you should be. This study was, more than anything, making a point about scientific method and the danger of overlooking details in actual research.

[Edit: Cutting to the chase, if you haven't read the article: although not immediately obvious in the study, the aircraft used were, for both control and experimental groups, parked on the ground during the experiment. The height of the free-fall was less than 1 m.]

This one reminds me of a joke about 6 people on a plane including a couple important dignitaries, along with the world's smartest man, and a hippie and a boy scout. The plane runs out of gas and they only have 5 parachutes. The dignitaries and the pilot took the first 3 parachutes, and jumped out, and then the world's smartest man argued that he should also get one, leaving the hippie and the boy scout with just one parachute between them. "Not to worry", the hippie tells the boy scout="I just gave my backpack to the world's smartest man." ## \\ ## In any case, in responding to the OP, I do think that it would help to have some training in what to do with a parachute, , as well as how to exit the plane, in the event you needed to parachute from a plane.

Now I'm concerned. Did the helpful hippie and the boy scout learn to glide the aircraft? Or gently float to terra firma in each other's embrace on a single 'chute (like GHW Bush on his 99th birthday)?

Postscript: lost count of the parachutes in all the excitement :-).
