If you love to play flight simulators, and you’re looking for a new challenge, then Flight Theory is the perfect game for you. In this game, you can explore the world of flight, from taking off from a carrier to landing at your destination. 

You can land on a variety of different airfields, from airbus and Boeing to the famous airports like London Heathrow and JFK. You can take off from different airports, and you can fly over different cities and mountains.

As you play the game, you will unlock new planes. The planes that you unlock will have different stats and abilities. For example, you can fly faster, carry more passengers, and have more range.
