Cause it was built to go into harms way? Cause the exposure was actually to a flight crew and not the ship itself?
Cause they know what they are doing?
Intentionally steering the ship into an area where there is a known radioactive plume when it is completely avoidable is a sign of them "knowing what they are doing"? Tell that to the sailor who accidentally breathes in a hot "flea" and dies a miserable death from lung cancer a year and a half from now. Seems like an unnecessary and completely avoidable risk to me.
