You can only go to the roosterpit (HEEHEE I SED rooster), I forget about auto-pilot.
You can view from other angles such as nearest airport tower (Not recommended for far away or landing), above the plane, below, wings, etc.
Real-world terrain, and weather is based on real weather updated every 15 minutes if you have internet.
Oh, and yes, it is VERY hard drive consuming. It's got the ENTIRE WORLD able to be flown in. Yes, you can crash in buildings and yes you can crash into the water. Yes, you can also fly in space but it's really hard and you can only get there by using the special positioning mode.
