  1. The FBI has assigned a FOIA number to my request for page KA-3 of the Facial Identification Catalog of 1971 (which includes image KA3-9). They had rejected a previous FOIA request, more broadly defined. Will post any further responses from the FBI.
  2. Somewhat to my surprise, I just received (by snail mail) a response to a FOIA request that I had submitted on 09.18.2020, regarding the "sled test" film. Instead of the standard rejection letter (of which I now have quite a collection), the FBI sent me the five pages below. I believe that the photos are familiar from n467us.com and from Ralph Himmelsbach's book, but I'm not sure that the two cover pages have been released before. The redacted name is presumably Capt. Thomas Spangler. I don't know what to make of the phrase "These will not be used". The five photos have only two variants. I have the impression that the tail number N467US has been drawn by hand on one image, and airbrushed out on another. 720110 164-81-1A p1.pdf 720110 164-81-1A p2.pdf 720110 164-81-1A p3.pdf 720110 164-81-1A p4.pdf 720110 164-81-1A p5.pdf
  3. My second calibration of KA3-9 was too wide in the horizontal axis. Here's a third calibration of KA3-9 based on the assumption that the page from the Facial Identification Catalog was standard US letter size (8.5" x 11" or 216 x 279 mm). If so, the individual photographs were about 39 mm wide by 49 mm high. The "Bing" sketch is shown for comparison, with eyeline and chinline matched.
  4. I agree. I recalibrated the image against a full page from the catalog, which I found on worthpoint.com.
  5. Here's a comparison of the reconstructed KA3-9 with the FBI sketch.
  6. Many thanks. Here's an attempt to reconstruct KA3-9 with perspective correction. Hard to see how this identification formed a basis for the FBI sketch.
  7. I have just received a reply to my FOIA request, submitted on 12.14.2020, for the relevant extracts from the Facial Identification Catalog of 1971. The FBI informed me that "potentially responsive records" have been destroyed. Does anyone on this forum have images of the KA-3-9 and KK-5-1 profiles, as they originally appeared in the catalog?
  8. Many thanks. The FBI stated that "The first search area was calculated using a system of plotting known as "GEOREF" (i.e. Geographical Reference) which has a plotting error of plus or minus one mile. A new plotting system using a computer generated latitude and longitude has a plotting error plus or minus 1/2 mile." However, if the FBI were using the term GEOREF as used today, to refer to the World Geographic Reference System, then their statement does not make sense. GEOREF, as used today, is a system of definitions and has no intrinsic errors. Errors only occur when something is measured. I imagine that the raw data from a radar plot would be expressed as two components: (1) a distance in nautical miles from the transmitter, and (2) a radial in degrees from e.g. true or magnetic north. For example, MALAY is 63.6 nm from SeaTac on the 197 degree radial (true); but an airplane at MALAY might be measured at a slightly different distance and radial, depending on the accuracy of the radar. The measurement error would carry over into any grid reference system that was used (e.g. MGRS or GEOREF), whether the translation was done manually or by computer; but the measurement error would not change. So it doesn't make sense for the FBI to say that a different system, or using a computer, would reduce the error of the measurement.
  9. Thanks, got it now (thanks to andrade1812 on DB Cooper Forum). This site converts latitude and longitude to GEOREF and other grids: https://www.earthpoint.us/convert.aspx. So the four annotations NC, NB, NA and NQ (from north to south) correspond to the GEOREF quadrangles DKNC, DKNB, DKNA and DJNQ.
  10. Has anyone on this forum contacted Captain Spangler, or does anyone know whether he is still alive?
  11. Agreed. Each of those annotations is in the lower left corner of a quadrangle bounded by degrees of latitude and longitude. The notations NC, NO/NB, NA/XA and NQ/NO don't correspond to any map reference in the Operational Navigation Charts or theTactical Pilotage Charts of the Defense Mapping Agency.

  12. Here's a question for Hominid and other experts on the "FBI map". Does anyone know the significance of the handwritten letters “NC” (abeam Seattle), “NO” or “NB” (abeam Pigeon Springs, Washington), “NA” or “XA” (abeam Salem, Oregon), and “NQ” or “NO” (abeam Eugene, Oregon)?
  13. Thanks for this clarification. Is this information from an FBI document, or from a JC Penney's catalog?
  14. This post is over 12 years old but ... does anyone know whether Ckret ever uploaded the film?
  15. Can anyone re-post these pictures? They don't seem to be on the site anymore.
