top free flight simulators

1. Aces High

Aces High is my personal favorite. It is an online WWII flight simulator. You can also do offline practice mode. There are lots of planes and vehicles. I give it a 5 star.http://www.hitechcreations.com/

2. Microsoft flight simulator demo

I like the Microsoft demo because it looks good and it flies nice. There are four planes and one helicopter. There are a few airports and two challenges. over all it is a fun demo. I give it a 4 star http://www.microsoft.com/games/flightsimulatorx/downloads.html

3. Flightgear

Flightgear is a nice free flight simulator, but it is hard handle. There are a lot of planes, and you can download more planes. over all it is a fun game. But I still give it a 3 star http://www.flightgear.org/
