Zc773. This is a picture of the Subic Bay Ship Repair Facility, I was a diver there and I remember diving under and inside the submarines many times at that location. It feels like home, looking at this picture. This picture came from this URL, click here!

In January 1982 five U.S. Navy divers died when a vacuum was inadvertently drawn in a chamber on Grayback off the coast of Subic Bay, P.I. The diving accident led to changes in how the Navy designed, built, maintained and operated complex submarine based diving systems.
The 6th diver survived and is a personal friend of mine and lives here in the greater Subic Bay area.
