Re: "I'll put my money on a Skylon."
nobody, the damage on the windows of the ISS is what space dust can do while not travel at any great speeds https://youtu.be/gfLnvEFkfMc?t=2m41s
if you have a submarine topological radar like https://youtu.be/KnhBUb0P8GI?t=3m20s
then you will need something that can easily be fixed if you are travelling at X MPH after compressing magnets, even the best radar won't pick up dust and you also would'nt be able to navigate around dust
