Ok apart from getting a life and enjoying the travelling what suggestions about the sim do you have?
- John how does apple do left and right mouse button calls?
- Check that right mouse button click anywhere even over the right hand side de-selects the currently selected plane.
- make the direction blue line an arrow
- what happens if you have planes head on (parrallel) but slightly off to one side. ie the predicted circle interlock but without ever touching? will the plane collide or will it detected the future collision?
