Dear Rob, I have just read your e-mail, regarding Voyager 1 and 2. As I am totally and absolutely convinced that NASA has not landed anyone, or anything, on the Moon, Mars, or anywhere else, and that their claims of "gravity slingshots" are total rubbish, you will appreciate that Voyager 1 and 2 are no trouble for me to explain - where they are I do not know, but one thing I do know is that they are not where you seem to believe them to be. I would therefore be far more surprised to learn that they are further out than the Moon, than I would be if one, or both, of them came down in your or my back garden. Having said that, I'm now back on vacation! Best wishes, Neville.

In a geocentric scenario, these 2 spacecraft are also, of course, now moving round the World at a speed of 2199114855 miles per hour, or 3.2 times the speed of light. Can you explain how they have reached this enormous speed, considering they have not fired their engines since leaving Earth, apart from for very small course corrections. I look forward to your considered reply. Thanks. Rob Glover. This e-mail and any attachment is for authorised use by the intended recipient(s) only.
