I never really liked the idea of the Space Jockeys even having a form of threat, carrying the eggs to use for battle, seems like ever other aliens race in the Aliens and Predator universe are hostile, there's no real peaceful ones, or not so aggressive, the Jockeys are closest to peaceful beings, it does get repetitive at a another race bent on killing or battle.
Also, in the novel, they never actually saw the dead Space Jockey, I think that what the rock formation was, but they found an empty egg and the weird transmission machine, which was some kind of metal rod moving back and forth, not a piece of dust or rust on it. But I can't remember reading or hearing anything about the ship crashing, looks more like it landed. I also like the idea of the ship being grown, instead of built.
