From: gwh%sandstorm.Berkeley.EDU@ucbvax.Berkeley.EDU (George William Herbert) In the last few days the US Navy has had one of those statistical clumps of accidents that drive Admirals up the Bulkhead. Sunday: a Training plane crashes aboard USS Lexington, killing five. Monday: A F-18 doing practice bombing accidentally hits the CG Reeves with a Mk 82 500 lb bomb. Bow damaged, five injuries. [in indian ocean] Reports indicate that the bomb was fuzed for superquick (instantaneous) detonation, and the damage would have been much worse had it penetrated into the ship before detonating. Tuesday: Two incidents: USS Eisenhower: Three sailors and 38 air to air missiles ($4.5 million) washed off a elevator while they were being raised onto deck. Two sailors recovered from water within an hour, one still missing and presumed dead. USS Carl Vinson: Sailor falls overboard and is not recovered. Cause unknown. It's been a bad week. [mod.note: The Eisenhower accident seems pretty odd... that must have been some wave ! Is it routine to operate the elevators in such weather ? - Bill ] **************************************** George William Herbert UCB Naval Architecture Dpt.

This is considered `moderate' seas and shouldn't cause any disruption to carrier Ops. Apparently the the wave that swept the elevator was a freak and was therefore completely unexpected.

I find all this surprising. Don't ships have lookouts any more? Just where
could the wave have come from?

Just where >could the wave have come from? .. There is, i believe, a phenomenon formally known as "the freak wave" (defined as "larger than whats running), it's not simply a phrase. This is dredged out of a Scientific American article read long ago. Origins of such waves were unknown at that time. I suspect that even if such a wave were spotted, there would be little that could be done, with the ships rigged together thanks dave pierson |The facts, sometimes fuzzily remembered, Digital Equipment Corporation |the opinions, my own. 600 Nickerson Rd Marlboro, Mass 01742 pierson@cimnet.enet.dec.com
