I'm sorry but that video is a load of bullshit.
I made it as far as the whimsical animation where a fully landen jumbo jet traveling between 700-800Km's an hour crashes into a building, and suggesting it should crumple up like a light aircraft traveling at half that speed.
I offer this: in 1992 in the Netherlands a 747 hit an apartment building after suffering mechanical failure.
It actual nose dived into the building.
The result of this massive of re-enforced steal and concrete building "that's so much stronger then an aluminium plane"?
The plane punched straight through it, in fact so little resistance was mounted by the building that **** pit made it out the other side almost fully intact.
The area of the building where the plane hit completely crumpled and collapsed due to the force of impact of the crash and fire that it started.
Here's a photo of the aftermath.
What it says about Newton's laws is correct,
Netwons third law does place an equal amount of force on both objects, but they aren't taking into account another of Newton's laws.
An object in motion STAYS in motion until it is acted upon by an opposing force.
And as an object accelerates it gains mass.
This means is that the plane will keep going in a forward direction until it is met with a force strong enough to force it to come to a complete stop.
Now keep in mind this SAME FORCE would also be acting on the building.
For the plane to keep going all that needs to happen is that the force acting in both directions is strong enough to move the sections of the building it comes into contact with, but not strong enough to cause the plane to come to a complete stop.
In this case the plane would be slowed but continue to move forward.
As the plane slows down this force acting in both directions is reduced.
But the plane would KEEP moving until such time as the mass in front of it capable of with standing the force acting upon it.
What people fail to understand is not the mass of the plane but the strength of the building, wer'e not talking about the strength of the entire building.
Only the strength of the PARTS of the building that the plane comes into contact with, if it over whelmed the entire building then the building would fall over, if not then only the parts that cannot withstand the impact shift.
Look at the plane as a bullet and the building as a brick wall.
For a bullet to go through a brick wall it only relies on it own speed.
Throw a bullet at the wall and what happens? The bullet bounces off.
It simply doesn't have enough mass to exert force on the wall to move it.
Fire a bullet at a wall and it goes straight through, by increasing the speed at which bullet is moving, you also increase the (relativistic) mass of the bullet.
Because the bullet is now moving at a speed fast enough that the force acting on the wall is greater then the parts of the wall it comes into contact with can withstand.
That's ALL that matters, so long as the object that's moving creates enough force, to shift the object it comes into contact with from its resting state to a non resting state the resting object moves.
To stop the object that is already moving the contact needs to create enough force to bring it to a resting state.
I'm sure someone out there can run the numbers and tell you exactly how much force is needed to stop a a 747 traveling in excess of 700km's. Per hour dead.
But I would hazard a guess that there isnt a man made structure in the world that also wouldn't be moved from a resting state by that same force acting upon it.
Because as the video stated that same structure would have the exact same force exerted upon it, inline with Newton's third law.
you can't just pick and choose which laws to take into consideration they all act together.
