Are U-TURNS par for course for cargo vessels on that Tokyo bay??
technically, the manuever took 25 minutes, but from what I understand in the dead of night with the bay having all sorts of shipping and fishing vessels, it may as well have been a few minutes...
The actual time of the collision is crucial in understanding the reasoning behind a u-turn by the Crystal. These latest reports seem to suggest the collision happened an hour earlier than first stated, meaning the U-turn was made after the collision. That would seem consistent with the Crystal returning to the site of the collision to offer assistance either to the Fitzgerald or in the search for lost sailors.
