yeah, that's just it. you CAN land 747's on whatever field it can fit on. Hell, you could even land it in the middle of a pasture, and then take off again. There's no preflight stuff, when you runoff the runway, it makes no difference. When you fly over the white house, it doesn't matter. you can't do spins. you can fly and land into any military base and ATC will not "yell" at you. you can fly into class alpha airspace and not need an instrument flight plan. you can get clearance to land at a class Brave airport and an airliner will probably rear end you. you can put in any emergency code in the box and ATC will not ask you if you have an emergency. It's just for entertainment. If any program actually did all that stuff, it would cost more than $29.99.
