This might be the one Mike was referring to... In January 2003, a
heilcopter on a tour in San Francisco was forced to ditch into the bay.

I just returned from a trip to California and spent 3 days in SF. Who flies
the LongRanger and 407 that does the tours of the Bay area? I see they have a
pad in Sausolito off 101. Back in 84 when I was last there they had a pad on
Fishermans Wharf that was used for the tours but if I recall the "powers-to-be"
tossed them out of there.
BTW, these guys fly in some very dramatic changing weather. One afternoon I
saw the 407 flying UNDER the Golden Gate Bridge into the Bay because the
ceiling had obscured the top of the bridge.
It could be sunny in SF and foggy/low clouds to the north or east. That has to
keep a pilot on his toes for sure.
