How do people survive a plane crash? A real one, from the sky, not on the ground

Shouldn't the force of impact and shit completely mush all passengers? Is crashing in a plane more or less severe than just falling freely from the same height? Does it soften the impact to be in the plane?

hey /sci/ i have a question. So I'm studying for a exam and I am trying to figure out how to prove this:

Prove that each member of the set of congruence classes mod 9 has an inverse with respect to the operation ?. (circle plus if its blurry)

please and thank you :D

Solve one of your choosing /sci.

Hard Mode : Solve Both

Can of you kind anons point me at some software that allows me to visualize a bunch of 3D elevation data in such a way that i can simply "walk around" in it?

More details:
I am doing groundwater modelling, and so i have 3 data sets:
bottom of the aquifer,
waterlevels
top of the landscape

all in text files with x,y and z. with around a million points

Actually the software i produce them with (GMS) does visualize it in 3D, but it is shit slow, and also i cant freely zoom and walk around in it.
I can easily plot that shit in matlab (pic related) but that is also not good to walk around in.

other suggestions?

tl;dr:
I want to walk around in my model, like in a 3D egoshooter game (weapon optional)

>Vatican spokesman Fr. Federico Lombardi said that while Christians "do not rejoice" over a death, bin Laden's death serves to remind them of "each person's responsibility before God and men," expressing hope that bin Laden's death "would not be an occasion for more hate, but for peace." The Vatican went on to say that Osama bin Laden must answer to God for having killed an innumerable number of people and exploiting religion.[74]

Ages ago it occurred to me that while electric cars are still way too expensive, there ought to be electric motorcycles out there that cost much less as they weigh less and thus would need less battery mass to go the same distance.

So I looked online and sure enough there were a few options out there. All the motorcycles had a price premium over scoots due to the cool factor, and as I really just needed a reliable commuter I went for a clunky two seater with a 4kw motor, does around 50mph and 30 miles.

But naturally I couldn't stop there and had to do something retarded like stick solar panels all over it. They don't do much; it takes 30 minutes in bright sunlight to restore 1 mile of range. Even so, I'm stuck at work for 9 hours, 8 of which are peak sunlight this time of year, so I can replenish 16 miles out of the 30 mile range in that time. Since my commute is around 4 miles and I usually drive 1 or 2 miles for lunch break, it's still sufficient to cover all of the energy I use to get around in the course of one day.

It's not lost on me that I can't possibly make my money back, due to the initial costs. But then my projects are never intended to be practical, just interesting.

Next: Upgrade to 30 watt panels for a faster charge, and maybe start thinking about converting my car to solar electric if I can find big enough panels for a sane price.

what are the evidences of bin laden death?

inb4 ad hominem huuurrr the government say so

I will personally carry the child of anyone who can point in the direction of a solution to:

Find integers m and n such that: 7 = 71m + 23n

Good luck with AP Chem tomorrow /sci/fags.

Tell me something /sci/
Say you have a function f(x):{1,2,3,4,5}->{1,2,3,4,5}. What's the number of functions | f(1)=f(2).
I believe it's 5^4 but I'm not very sure.
