So now that we have a model for predicting historical surface currents around Point Reyes, and we have an estimated time for the ditching, what does our model tell us? We take the estimated ditching time of 6:25pm, and add 2 hours and 15 minutes to get the time (8:40pm) that we will use on the September 21 2017 surface current charts. Posted here are the surface currents for 9pm around Pt Reyes. As was earlier guessed, the current flow is pretty much all south. If coupled with a wind generally from the north, then the ditching spot of the plane will be well to the north of the landing spots for Lt Anderson and Private Eastwood. As stated earlier, I'm not sure how accurate this hindcasting of surface currents is. Perhaps its totally meaningless. But the general flow around Point Reyes is southward, so to me this just verifies that we're not dealing with some weird spot in the tidal cycle where the currents reverse and the flow along the coastline is northward.
While NOAA does not have on-line tidal data dating back to 1951, they do have a Tidal Prediction Site, based upon harmonic coordinates that have been carefully measured at certain stations........and it turns out that the southern tip of Point Reyes is one of those stations. Station #9415020, to be precise. So I can hindcast the tides for the times around the evening of 30 September 1951, and then try to find a modern date that is a reasonable match to the tidal cycle, for which there will be surface current measurements. I'm not sure how scientifically accurate this process is, especially since I don't know how surface currents might be affected by the local winds and weather, but it's probably the best I'm going to be able to do. Finding a reasonable match for the tidal cycle turned out to be pretty easy. The tides on the evening of 21 September 2017 are a pretty close match to those of 30 September 1951, with the 2017 tides occurring about 2 hours and 15 minutes later. I've attached plots of the tidal cycle from 29 September - 1 October 1951, compared to the tides of 20 September - 22 September 2017.
So what time was it when Lt Anderson ditched his Skyraider? One would think it would be easy to pin down such a basic fact, but that's not the case. The Navy's accident report lists the time of the accident as "1825U". I'm not familiar with the use of the letter U for times (as opposed to the letter Z for "Zulu time" or UTC), but it seems reasonable to assume that this is local time- 6:25pm. The article in the Independent Journal says that the operator at the RCA radio station encountered Private Eastwood at about 6 pm. That would put the time of the ditching as likely before 5 pm, as Pvt Eastwood is recorded as having struggled in the water for some period of time before making landfall near the RCA transmitter. The article in the Chronicle says that a radio message was picked up from the Skyraider at 6pm, when they were still some ways off of the Pt Reyes coastline. It then goes on to say that Lt Anderson called in from a ranch-house phone at 9:25pm. In this case I'm inclined to believe the Navy report and the Chronicle article, since they are consistent with one another. We'll assume that Lt Anderson ditched his Skyraider at 6:25, and examine the predicted surface currents around Point Reyes for the next couple of hours after that.
On 30 September 1951, two Navy AD-1 Skyraiders left NAS Seattle in Washington for a routine flight to Mather Field in Sacramento, California. One of those aircraft had radio problems, got separated from the other in bad weather, and then got lost. While the pilot eventually managed to break into clear weather, he ran out of fuel while flying down the California coast north of San Francisco. The pilot made a successful ditching, and he and the one army passenger got into life rafts and paddled to shore. Maneuvering through the rough shore break was not so routine, and the passenger nearly drowned in the process. Most incidents of this type tend to get lost in the sands of time. The pilot of the unfortunate flight died a number of years later. The passenger however, is still alive. He left the army and has gone on to have a long career as a movie actor and director. That man's name is Clint Eastwood.
Even once we've figured out where Lt Anderson and Private Eastwood came ashore, to make a good guess as to where the aircraft is we'll have to know what the surface currents were. Present-day surface currents along the California coast can be seen on this site, with a spatial resolution of 2 km and a temporal resolution of 1 hour. If you check the area off of Point Reyes, the typical surface currents run north to south, although at points in the tidal cycle this can reverse to a south-to-north flow. To get the best estimate I'll need to find precisely where things were in the tidal cycle on the evening of 30 September 1951. Some historical tidal information is available on-line, but I haven't been able to find historical San Francisco tidal tables. Looks like another trip to the San Francisco Library is in order. The attached images show the extremes of surface-current flow during the tidal cycle.
According to the article in the Independent Journal, Private Eastwood wandered into the RCA radio station after coming ashore. This landmark is easy to find, as it's still around- they're referring to Radio Station KPH, which was located in a famous art-deco building from 1929 until its closure in the late 1990's. The building has been preserved and is part of the Point Reyes National Seashore. You can read about its history here and here. The radio station KPH building is located about 3/4 of a mile south of Abbott's Lagoon, well back from the beach. As was indicated on Mike Warner's Flickr site, Eastwood probably came ashore at the beach immediately to the southwest of the lagoon.
So my "go-to" source for aviation archival work is Craig Fuller at AAir. I dropped him a line to see what information he had available about the ditching. A couple of days later I got a dropbox link with scans of some photos, Navy reports, and the same newspaper front page (The Independent Journal, San Rafael, CA, 1 Oct 1951) that was on Mike Warner's site that I linked below. I suspect that Craig was the original source of the archival information. The accident report runs several pages, but the relevant stuff is on the second page, regarding the details of approaching the Pt Reyes coast and the subsequent ditching. The newspaper is even better, with details of where the pilot, Lt JG Francis Anderson, and the passenger, Army Private Clint Eastwood, came ashore. I'll have to round up some detailed maps of the Point Reyes area to see where Kohoe Ranch, Pierce Point, and the RCA Radio Station are (or were- these are details from 66 years ago!)
Quick searches of the internet don't reveal a lot of information about the ditching. There are a lot of articles where Mr. Eastwood recalls the incident to a reporter, such as here and here. These are interesting for context, but they don't provide much in the way of solid information upon which to base a search. The Wikipedia article for Clint Eastwood mentions the incident briefly, with three footnotes. But those footnotes lead to biographies, not to contemporaneous source documentation. The biographies might have footnotes that point to the original material, but it's going to take some legwork to track that down. A careful look at the Wikipedia page shows that there's a separate article for his early life, and this article has much more detail on the ditching, including the date, with a new set of footnotes. Peering into the footnotes, we see that one of those is the Navy's accident report for the incident. Now here's some material we can use. There's a local newspaper account as well, from the day after the ditching. The copies on the website are a bit fuzzy but can be read in a pinch. I'll try to round up some better copies. Now we've got a starting point for researching this thing.
After hanging up the phone with Russ, my thoughts immediately drifted to whether we at OpenROV could find the ditched aircraft. Step one, pull open the chart for the area. The NOAA charts for Point Reyes are 18643 and 18647. Looking at these, the bottom looks to be relatively flat and not too deep- three miles off of Point Reyes the depth is around 60m (200'). That's a depth we can get to with our sonar and our ROVs, and a smooth bottom will improve the visibility of targets in the sonar data.
This whole adventure started at the end of July. Here at OpenROV we were looking for some interesting sites on which to test our new Trident ROV. We've been doing a lot of work in Monterey Bay and San Francisco Bay, and it was time to step up the intensity of the testing. We started looking for interesting targets around the Farallon Islands, which are about 30 miles off of San Francisco Bay. One idea that came up was to survey the wreck of the USS Conestoga. The story of USS Conestoga is an interesting one. In 1921 she left the San Francisco area for Pearl Harbor in Hawaii, but was never heard from again. The fate of the ship was unknown until very recently- her wreckage was picked up in a 2009 NOAA multibeam survey of the area around the Farallons, and then was identified with two ROV surveys in 2014 and 2015. In looking over the online documentation from the 2015 survey, I noticed that one of the participants was a friend of mine, filmmaker and aircraft historian Russ Matthews. I decided to call him to get some background information on the conditions surrounding the wreck of the Conestoga. It turns out that there were a number of interesting targets seen in the multibeam data, and NOAA was trying to identify some of these. One of the targets they hoped to identify (but did not) was what might be the remains of a Navy Skyraider that had ditched off of Point Reyes in 1951. This naturally got my attention, as aviation history is an interest of mine. Russ mentioned that one of the crew members from the ditching is still alive, and that further got my attention- it's great to have the ability to connect the past to the present, through the eyes of the person who was actually right there. Then Russ mentioned that the crewmember's name was Clint Eastwood. BOOM! Archaeology isn't about rock piles and weathered timbers and twisted aluminum, its about the human stories that those objects tell. This particular story just got way more interesting.
The article in the Chronicle had similar information, but not the same. Was this a case of two reporters giving different interpretations of the same information, or did the two reporters have different sources? In this article, the plane was ditched two to three miles offshore, but five miles north of Point Reyes.
A few days ago I went to the San Francisco Public Library to check out what the two main San Francisco papers, the Chronicle and the Examiner, had to say about the ditching. It turns out that they had some useful tidbits of information, some of it contradicting other material that I've already gathered. So it goes with historical research. Here is the article from the San Francisco Examiner. According to the article, the plane ditched "five miles off Point Reyes", the pilot Lt Anderson came ashore 12 miles north of the Point Reyes lighthouse, and Private Eastwood came ashore five miles south of Lt Anderson.
