USS Fitzgerald

How the hell can a Navy destroyer get T-boned by a huge slow container ship? I mean, these ships are fast enough to tow a water skier behind them, have about 10 different radars on them and all kinds of redundant collision detection alarms. WTH? I am glad they found the 7 souls but that boot Commander (1 month!) has ALOT of explaining to do....At 0230, I expect a sleepy non rate seaman at the helm, but there are always fore and aft lookouts posted.
