i can now break the blocking of internet by theing communist party now,so which video tutorial should i watch on youtube?
"When injustice becomes law, resistance becomes duty." Thomas Jefferson
Take a look at TexFilms (great tutorials and a great film maker as well)
David Courtney also has some very good tutorials
Since Orbiter and science videos are not political or commercial I don't think it's a problem trying to see them.
Just a quick vote of support for David Courtney's videos. He did a TON of them and they are awesome. I loved how he started with the most simple maneuvers and ended up with super-complex things. If you haven't done a Mars trajectory plan for a while, it's always worth reviewing these videos to refresh yourself.
David - if you are still out there: hope things are going well with your recovery. True Orbiter Hall of Fame candidate here.
