Come on. When you have companies like Boeing unwilling to even build a plane right, you'd actually expect them to add parachutes and not cheap out on them?
Let's be serious here.

"okay everyone, stand up calmly and put on your parachute while the plane falls out of the sky.. once everyone is done with that, and all parachutes are secure, we will begin an orderly de-boarding.. thank you for your attention - while the plane falls out of the sky for some reason.."

[–] [email protected] 4 points 7 months ago (1 children)

Right, the question definitely sounds incredible silly when you put it like that haha, but fair point. Was more thinking it would be better that some survived than none, but indeed: on a full passanger airplane this would probably never work out.

People can barely get off or on a stationary plane in an orderly fashion.

There would be people climbing over one another and seats, people getting trampled, Stooging at the doors, people getting knocked out of the door without a parachute, and people falling to their death because they didn't put the parachute on right or they exceeded the weight limits of the equipment due to their American figure.

In other words (and more neutrally), there have not been any randomized controlled trials of parachute intervention, so we do not have data to say whether they would work or not.

[–] [email protected] 3 points 7 months ago

This is satirizing the view of people who feel observational studies - studies in which everyone is treated with the experimental medicine and the response of the entire group is evaluated - aren't clear enough or rigorous enough to prove that a drug works. True, these studies sometimes lack the clarity of a perfect randomized double-blind study, but as we see with the parachute, sometimes the results are pretty clear anyway. And in a life-or-death situation, no one wants to take the chance on a placebo. In other words, the "advocates of evidence based medicine" are being "challenged" with a little sarcasm.

Imagine being part of that experiment.

“Here’s your parachute. Hope you aren’t part of the control group!”

[–] [email protected] 7 points 7 months ago (1 children)

this is satire/trolling, not an answer.

[–] [email protected] 1 points 7 months ago* (last edited 7 months ago) (1 children)

Yes, I know, I thought it was obvious that it's a joke...

[–] [email protected] 3 points 7 months ago

fair, but wasn’t obvious to me so i figured i’d share my findings for others who didn’t get the joke.

People don't want to wear a facemask. Imagine a parachute. We are truly garbage.

It works for the Cirrus because that plane is tiny. A parachute big enough to safely land a commercial jet is not feasible.

If a commercial plane has a failure, say an engine failure as in the news story, the pilots with fly the plane with the other engine to a safe landing.

If the Cirrus has an engine failure it becomes a glider. If there's no airports nearby you'll have to ditch in a field somewhere. There is a lot less redundancy in general aviation.

If you're a new pilot buying your first plane, having a parachute on the plane is a nice feature.

[–] [email protected] 6 points 7 months ago

If a comercial plane has both engines fail and can't be restarted, it also turnes into a glider, a small wind turbine will deploy and power basic instruments and controls, check this out:

Hahaha I didn't think the odds for the life vest execution would be so bad, and that's way more simple than a parachute.

lol I watched this like yesterday

I'm sorry for whatever you see in there 😭

Cuz based on the type of accidents, it probably wouldn't make sense. It is just adding extra cost.

Short answers from the video: (but its a good video if you have the time)

  1. They weigh a huge amount and take up a lot of space, so carrying them on every flight would be crazy expensive for extra fuel cost and reduce other baggage cargo that could be carried.
  2. Current day passengers have difficulty just putting and keeping a simple seat belt on. Properly putting on a parachute, especially in the small space you have in an airliner, and successfully deploying it outside are beyond what airline passengers are capable of doing.
  3. Passenger jets fly too high and too fast to survive jumping out of one at cursing altitude. Even if you successfully put on the parachute, got out of the plane without being sucking into an engine or hitting a control surface at 400MPH, you would quickly suffocate from lack of oxygen and/or freeze to death from the sub zero temperatures at that altitude.

I like your point #3 the most. We're at #$!@ 30,000 feet, you bastards!

[–] [email protected] 5 points 7 months ago (2 children)

Specifically about that third point, how long would it take to get into a "livable" range if you were free-falling? Like obviously hypoxia is a legit concern, but are you going to get out of that range quick enough to avoid real complications?

[–] [email protected] 3 points 7 months ago

I have no idea what a livable height is, but it take about 3 minutes to hit the ground falling from that height (obviously there is a lot of error here depending on the exact person).

Parachutes require pretty specific conditions to be able to use, and they require a fair amount of know-how. Expecting random passengers to be able to operate a parachute at all is basically a losing battle, and if you had people jumping out of planes that were on their way down, you'd have a lot more people dying (speculation but I'd wager money on it) than if they just stayed in the plane. Plus it'd be a horrible look for the airline - even worse than a plane crashing and killing everyone on it - if they had dead people raining down over cities and whatnot because they jumped and didn't properly deploy their chute, or deployed it too quickly, or didn't jump at the right time and got hit by the plane or any number of other possible problems.

Fighter jets and the like have ejection seats that specifically propel the pilot away from the plane before deploying the chute, and recreational (or military) planes that people are jumping from are designed for that purpose, and are moving a lot slower than commercial airliners. Opening the door on a plane to let people jump would cause more problems than keeping them on the plane. (People getting sucked out the door and the like.) Getting passengers safely clear of a plane that's going down unrecoverably would be basically impossible.

This guy was in a remote controlled, parachute equipped gondola at 17km altitude wearing a pressurized suite. His suit broke and even though the emergency descent of the gondola was immediately activated to descend safely, he later died from embolism (bubbles forming in the blood because of rapidly decreasing pressure). Passenger jets cruise at about 11km so i gather it would be similar.

Plus a lot of flights are above ocean or rough terrain a lot of the time, limiting the possibilities even more.

[–] [email protected] 41 points 7 months ago (1 children)

Commercial airlines also fly really high up. If you were ejected at cruising altitude, the first thing you would do is pass out and fall for a few minutes. Hopefully you wake up in time to orient yourself and activate a parachute.

[–] [email protected] 14 points 7 months ago (7 children)

That's not to say you couldn't have an auto deploy mechanism at a given altitude. I haven't skydived (skydove?) in years, but isn't there an emergency deployment mechanism if the chute hasn't deployed by a certain altitude?

Ah, yeah this makes total sense actually. Thanks for the insight!
