YSFlight

Shoot down waves of hostile aircraft offline, demolish nearly any ground object with any weapon, or challenge other combat pilots online to test your mettle as a flying ace. Use the navigation instruments to plot a peaceful flight, or hunt your prey with air to ground missiles, coming in for the kill with a hail of gunfire. Fly aerobatic formations, fight in ultra-lights, or land a strategic bomber on a helicopter pad. The only limits are your imagination, your add-on collection, and the rules of the server where you fly.
