Thanks Cmdr Chavik, about "Singe" it is very explanative. My english is not so good (forgive me about that).
I have some questions about UC information (This is not clear for me, and, please SC if you could spend your time with me...), but I'm not sure about how do it, without a "bad" english language
1)The first question is : have I yet in UC, space flight sim ?
2)have We will a move transition between space and planetary surface ?
3) Roam flight are there ?
thanks a lot
