Mass extinction from Star Destroyer crash?

[kerbiloid]

Star destroyers should be made of very heat-resistive alloys.
Otherwise the enemies would just drop a pack of yoda-ninjas onto its surface, and they would cut holes with their light sabers.
A thin metal layer (say, armor or door) is usually cut through without visible efforts.

Even in the prequel era before the Jedi purge, lightsabers were extremely rare. Wookiepedia states there were around ten thousand Jedi, which sounds like a lot but in a galactic population of quadrillions it's a drop in the ocean. Trying to land on the surface of an enemy starship would be plain crazy, risking the lives of your elite peacekeepers doubly so, and not something starship designers are likely to worry about. In any case Star Wars has specific anti-lightsaber materials, but they're rare. The most important doors (ie whichever ones the heroes need to get through!) might use them, and some lightsaber hilts themselves are made of them for obvious reasons.
