Wow John. Those tanks look like a lot of clutter. Must've been like swimming with a car on your back. TD TD, I've been trying to think of how to reply. Here's my dive logs for those dives: Now, to put this into perspective, I had left DaNang, Vietnam and the 37th Aerospace Rescue and Recovery Squadron on June 9th, 1971. I arrived back in Oregon to my parents house on June 10th or 11th, right out of the war zone. Then I was diving in Clear Lake on June 14th, while my family was on vacation in Eastern Oregon fishing and hunting. I was sorta the outlier in our family, as no one else dove, and every time I went fishing, I got frustrated and wanted to be in the water with the fish. Also, I had dived on September 18th 1970 with Joe Russel and he talked me into doing these dives when I got back (I had extended my enlistment to go to Vietnam, then gotten an early out off my extension to go back to Oregon State University for summer school). In between, I dove on this project. I was probably in the best shape of my life, and I made no mention of the equipment I had to drag around. Mostly, I was in the water with this gear, as the barge they dove off was anchored, and all I needed to do is get hooked up, walk to the ladder, and enter the water with these three tanks and the two other sensors (I had electrocardiogram leads taped to my chest too). Once in the water, it wasn't too bad, although a bit awkward from what I can see in the photo of my descending. You can see that the water temperature was 42 degrees F, and the depths of the dives. I did not record anything bad about the drag or the equipment, figuring it to be simply necessary for the study. Also, I was used to jumping out of planes with about 150 pounds of gear on into water, so I don't think that bothered me much at the time. Now, well that would be a different story. Note that the last breath-hold dive of June 16, 1970 had a remark stating, "Ne Mask." The researchers wanted to know whether the use of a mask had any impact on their physiological data for breath-hold diving; I don't think so. I dove that dive to 25 feet for 30 seconds, sans mask, in 42 degree water, just as a comparison for the dive #25. John John I know this a bit off topic from the chest mounted double hoses but you mentioned you carried 150 pounds of gear as a PJ?! What was in there? I think some new divers today could compare to that with all the gear they carry. Sometimes it looks as if they're carrying 150 pounds. There's nothing more underrated than minimalist and streamlined today! TD

TD, when our friend John finishes his book, you'll want him to autograph it for you, this story is nothing from the parts I've read of it Jaybird JB, I am actively working on the book, tentatively titled, " Between Air and Water, the Memoir of an USAF Pararescueman." Jay, are you familiar with Scrivener? I'm writing it in Scrivener, and have almost half the chapters finished. I'm now reviewing my diary entries from Bermuda, and expanding the NASA work we did. Here's a diary entry that I just forwarded to a gal who's putting together an exhibit for NASA of USAF Pararescue involvement with the NASA program. We would go on TDY (temporary duty) to destinations around the world, including Panama during Apollo shots. When I reference the "Panama crew," I'm talking about a deployment in support of Apollo (probably Apollo 12). It was pretty boring duty most of the time. TD, This will give you an idea of what we carried when we jumped on a mission over water for parascuba. This is from a PowerPoint presentation I have for school kids about Pararescue and the Vietnam War. Now, to get back to the topic, here is one of the sets of triples I have pictured from the U.S. Navy, but is in the exhibit in Tacoma right now (a part of Ryan Spence's collection). Note the regulator is slightly off-set because of the valve, which I mentioned in a post above. John

Laurie Hannola, owner of Pacific Watersports, my LDS, has this set of triples in her display window. This appears to be the original U.S. Divers Company triple set that was seen on Sea Hunt (not this set, but this setup). Note that this is a symetrical set, with the regulator mounted right over the center tank. John

Smart, that setup. Easily accomplished centered manifold.
