Yes I know about those results, and if they were massless they wouldn't be
useable as tachyons. Cramer suggested they might be tachyons if they had
negative mass values. Aren't atmospheric anomaly neutrinos muon neutrinos

If neutrinos were tachyons they'd need to be produced in a coherent beam,
else there'd be NO net thrust, aside from the slight absorption by the
ship's structure. Neutrino reactions with the chlorine and other neutrino
reactive atoms in our bodies would kill us before there was a useable thrust

Also note the report was of a mass DIFFERENCE between neutrino species, not
the actual mass. The case is still open.
