I considered that. I have never gone parachuting before but I understand they are considerably large.

You make the best point though. The teeny tiny chance is not likely worth the billions of dollars and the possible carnage.

Obviously people wouldn't be jumping out at max height. The plane is falling... therefore you're likely to be several thousand feet lower by the time you even know to get out.

Easy there Charlie's Angels. I think you've watched too many actions movies and smoked too many bowls.

Is this a serious thread? Are you serious?

Is she serious?

At some point, someone in the industry figured that at the rate aeroplanes don't fall out of the sky, that they can save millions of dollars every year in profits by not caring if you and a few hundred people ditch into the dirt without a parachute.

Your airfares are cheap for a reason

Not to mention the horrible technical challenges, lets see...

How many parachutes are actually functioning and stay functional flight after flight.

How do you design a one size fits all harness that can fit an infant to a full size adult, not only a full size but overweight individuals.

Make a reliable altimeter system to deploy the chutes and also make sure the chutes can deploy at lower altitudes.

As you can see by this graph from http://www.planecrashinfo.com/cause.htm most accidents and fatalities occur in either the beginning or ending phases of a flight when altitude is actually quite a bit lower than cruising altitude.



Most actually occur either on take off or just after or right before landing or as the plane has landed. Parachutes would be useless in these situations unless every airline seat was a zero-zero ejection seat capable of safely lifting the passanger up and away from the aircraft using small rockets (these are the same type of ejection seats in fighter aircraft).

Why? Because I don't know whether planes depressurize during a crash? *confused*

LOL! Yes Bas, I was serious.

When people are thinking about things, it's sometimes hard to think of all the ways your idea is stupid and wouldn't work. I come to TA to have people help me out

I know they love to do it... and I am a people pleaser, so here I am!

Also...

Basically, most people wouldn't be able to walk in a falling airplane. There's also the fact that the fall itself would knock you unconscious so it's not like people are screaming and flailing their hands to the very end.

How many G's would you get when jumping out of a plane going that fast?

Humans can sustain upwards of 9 G's for brief periods of time. If you deployed a parachute, you wouldn't have as many G's as you initially did when jumping out.

With that being said, if you were to stay in the plane and go down with it, would you likely be passed out long before you even hit the ground?

Anyway, I get that it's a dumb idea, just discussing now.

What is wrong with you? What kind of asinine questions is "why don't people have parachutes when they fly". Jesus.

Uh... Technically in free fall you have 0 gravities I think...

Also, read my posts I already said you'd pass out, thats why they have the masks.

I don't know if you are joking or not but yea... This thread actually made me a little angry lol.
