In | To celebrate Yury Gagarin's historical flight, [[Vostok-1]] carrier and spacecraft were added to FlightGear. In heavy development still, it already allows full orbital flight from lift-off to landing, making it perform the first spaceflight in FlightGear. | ||

Each single stage of the flight has independent mass scheme, propulsion system, aerodynamics reactions, so simulation is more or less realistic. | *JSBSim property driven point masses, tanks and engines, and aerodynamic coefficients implementation allow stages changing.

In real life, the first human spaceflight was fully automated. In FlightGear, instead controls are completely manual to make it interesting, and to make you understand how it really works. | |||
Authors and developers, since orbital flight is possible in FlightGear from now on, you are invited to make a FlightGear driven Mercury-Atlas project. Low earth orbit flights can be more exact and eyecandy in FlightGear than in any current simulator. And you can be sure it will be free for you and users in any case. | Authors and developers, since orbital flight is possible in FlightGear from now on, you are invited to make a FlightGear driven Mercury-Atlas project.
