No, but if you're inside a relativistic starship (or time-machine, in my
fanciful version in DREAMING DRAGONS), that's a lot of compressed sleet all
at once... I get more and more worried about the hazard of travelling
fast. Nano streams catapulted to near c, the front-runners taking the
ablation shock (but maybe, alas, adding to it in secondaries), sounds like
maybe the only plan that's safe against wear&tear.
