In TFA“The Force Awakens,” the Millenium Falcon seems to withstand impacts that would crush a normal Earth machine.
First, when Rey steals it and has trouble getting it to take off, it rams into the ground at high speed. Then when Han crash lands it on the Starkiller base decelerating from light speed (!), smashes through the forest, slamming into the ground and violently skidding to a stop against the rocks in front of a cliff.
What the heck is the Falcon'sFalcon’s hull and structure made of that it can withstand this force? Or is there some kind of forcefield cushioning it?
