During a discussion here regarding what color red to use on a Snark, I mentioned I had visited a USN Regulus I crash site on Oahu in 2000. This drone happened to be painted mostly overall Insignia Red, though I think the bottom of the wings were left in Gloss Sea Blue.
I thought maybe some of you might like to see what was left of the drone--not much. The Navy removed the sensitive components and probably the engine.
In 2005 (edited) while assigned to the Joint POW/MIA Accounting Command (edited)doing POW/MIA investigation and recovery, one of our civilian employees mentioned her cousin came across aircraft wreckage in Halawa Valley while hunting pigs. My ears immediately perked up, as legend has it there is a missing B-17 in this valley (no one has ever come across any records of this). I arranged a weekend to head up to the top of the valley high in the Ko'olau mountains.
Chris and I left early one morning on bicycles (mostly for the free trip downhill on the way back), meandering back and forth on the old access road underneath H-3, going almost all the way up to the top ridge of the Ko'olau's. We had to ditch the bikes and hike up some very slippery, wet, mossy and smooth boulders until we reached the wreckage.
I had visions of the lost B-17 in my mind, so I was immediately stumped by the complex nature of the wreckage and all the red paint. I had no idea what I was looking at. It was old, but the skins consisted of a strange form of sandwich construction, and some of the wing skins were made from heavily milled solid construction. I was at a complete loss as to what aircraft this was. Chris and I tried going up the very steep hills to see if we could find more wreckage, but it appears the main impact site was still much higher and would have to be approached from a completely different direction (from the top of the ridgeline). We abandoned that approach.
Chris, who is Hawaiian, must have developed a certain trust in me and asked if I wanted to see the burial cave behind a waterfall not far away. SURE! So off we went going up another steep ravine. We had to pass through a vertical slit about six feet wide (I could touch both sides of the canyon walls) to enter the final waterfall just 60 feet below the top of the mountain ridge. We were completely soaking wet, it was raining and 100% humidity, plus we had just slogged our way up the ravine mostly in the water. Chris said the cave was directly behind the waterfall, but I declined exploring it out of due respect to the Hawaiian culture (it is a fact that ancient Hawaiian burials were sometimes accomplished in caves such as this). We took a few pictures, and then, shades of King Tut, my camera died, never to take another picture again. AHHHHH. Actually, the long time we spent in 100% humidity killed it. At least that is what the repair shop said!
We then set off down hill, one mile in the ravines, then six miles on the bikes, easy huh? I thought I was going to kill myself. The heavy rain crossing the meandering road washed thick Hawaiian red dirt across it, but now it was mud. Our brakes became coated in the mud and didn't work, we kept going faster and faster. I put my feet on the ground, ala' Fred Flintstone, to try to slow me down but it had no braking effect, though it did keep me erect and from going into the woods. After a mile or so we left the heavy rain and our brakes resumed working. It was a nice ride after that. And a great little adventure.
After some serious research I found out this was Regulus I FTM 1476g launched from the USS Tunny in 1958. It was escorted/flown by two accompanying FJ-2 or -3s, but the Regulus lost communication with the jets and flew uncommanded south over Oahu, heading directly towards Pearl Harbor, shades of Tora Tora Tora. Fortunately, about ten miles north of Pearl Harbor, it pitched up, reached 20,000 feet, then spun down to crash in the mountains.
Did I mention one of my modeling desires is to turn the 1/72 Gato sub into the Tunny with this Regulus I on the launch rails. It will happen!

Sorry for the rambling. Here's the pictures:

Strange fasteners, it turns out these were for the balsawood-cored skins, an early form of what became honeycomb panels:

Me, soaking wet. Behind the waterfall is the entrance to the cave:
This is the narrow canyon wall you must pass through to get to the waterfall, it is only six-feet wide at one point. This is also the last picture my camera ever took:
Here's a different Regulus I being launched off the USS Tunny:
