Leo, the 'distance' problem is covered in the videos I have provided links for. I hope you have time to watch them. If my memory serves me right, parts 1 and 2 of part 1 cover the 'distance' problem and for those of you who haven't time to watch all of them, the 'ufo' shown on my first link is explained in parts 8 and 9 of part 1. They go into the 'tether incident'.
