The [[UFO from the 'White Project' of the UNESCO|UFO]] aircraft is a superb tool for placing a new (or old) 3D object at any arbitrary location in the scenery with just a few clicks of the mouse. | The [[UFO from the 'White Project' of the UNESCO|UFO]] aircraft is a superb tool for placing a new (or old) 3D object at any arbitrary location in the scenery with just a few clicks of the mouse. Placing objects in the scenery is a really easy way to contribute to the [[FlightGear]] project. It does not require any programming knowledge, and you can contribute something valuable in just a few minutes. | ||
This article gives an overview of placing, editing and saving objects using the UFO. You can get a list of flying controls and editing commands by pressing the ?-key while flying the UFO. | |||

The first line | The first line identifies the location of the scenery file for the object. The OBJECT_SHARED line indicates the object's name, longitude, latitude, altitude and orientation. This can be read by FlightGear itself and can be [http://scenemodels.flightgear.org/contribute.php submitted] to the FlightGear Scenery Object Database. | ||
You can also save these coordinates into your own scenery file so that your changes will not be lost the next time you start FlightGear. | You can also save these coordinates into your own scenery file so that your changes will not be lost the next time you start FlightGear. | ||
