Hackers are people who have fun messing with computers. Crackers are people who crack into peoples computers and destroy or alter their settings. Anything can be cracked into, some are just smarter then others when it comes to protection.

I have had a chance to use AeroFly Pro and G2 and FMS. Aerofly professional is definately the best, with g2 being nice for just making cool aircraft, and FMS if you dont have any money
