Lift is a flight sandbox game. It is based on real world physics, but what you build is completely up to your imagination - from Superman to WWII bombers and everything in between. Compete against your friends in challenges, or play in sandbox mode where anything goes. Time manipulation and plane destruction features allow you to watch your beautiful creation crumble into dust frame by frame when you crash. Early alpha versions are free to play and will be released in Web, PC, and Linux form.
The planes in these images were built by the community. I call them planes but as you can see the creativity of the community has left the realm of planes and entered pop culture and wildlife. They all still follow the rules of flight though, and as such some of them are a bit tricky to fly.
Love the toybox-feel
