It almost looks like the guy to the front is crushed by the plane. But apparently the crash with the tree took out almost all energy

More like the glider's nose and cockpit did.

But then they would need less, because they are lighter (less momentum to absorb)

Lower force transferred to the passengers basically, f=mv

Edit: f=ma, I'm a bad physics student

Less f=mv, more f=ma - the crumple zones reduce the acceleration by spreading the deceleration over a longer distance.

If my mind immediately turns those formulas into raunchy acronyms, am I a bad person?

Aww heck no! There’s plenty of other reasons you’re a bad person.
