All during WW2 he was interpreting photographs of enemy targets in the Pacific theater. Was married in 1945. Joined NAVPIC in 1946 and was there until under the CIA in 1953 (apparently this is the year that Lundahl formally became CIA himself). NAVPIC saw the Great Falls and Tremonton films arrive at the organization. Lundahl was in the NAVPIC front office by then, so did not do any of the analysis himself. But he knew the guys, Woo and Neasham, well, and was interested in what they were doing. He remembered very clearly the request from the CIA to have personnel bring the films to a scientific panel for review. Either because of this or even previously, he had a strong interest in UFO cases especially involving film. His actual job began to emphasize interpretation of U-2 photos. Early in the 1950s. (c.1954) he became President of the American Society of Photogrammetry and Remote Sensing. (I have no idea if this presidency demanded a cover job like Fred Durant's involvements in astronomical and rocketry societies did.) He attended a large (c.100 attendee) meeting held by the ONR on UFO information in 1955. Whether this was the final review given by the USN sideline UFO study project initially ordered by Navy secretary Kimball is debated. In the later 1950s, he consistently briefed Ike on aerial reconnaissance and became an influential person in "secret Washington". He also began collecting a file drawer of unclassified UFO photos; whether he also had a drawer of classified UFO photos one may guess. It is suspected by Australian researchers that PIC received the famous Tom Drury film during the early/mid-1950s, and that Lundahl probably knew about it. As a probable irrelevant sideshow, he was briefly involved in the infamous "Mrs. Swan Psychic UFO case", which also drew in Colonel Friend for a while. (c.1959). He constantly briefed both JFK and LBJ, and is considered an American hero for advice given during the Cuban Missile Crisis in 1962. Maintained an intense interest in UFOs during the 1960s, amassing a huge library of UFO related books in his home library. Met with representatives of the Colorado Project in 1967. This meeting was general in tone, but could have served the purposes of both parties. Colorado could get the services of the best photo-analysts anywhere for free, and Lundahl would get to personally see whatever came to them first hand. Colorado stuck with Hartmann and never took him up on anything. Due to Jim McDonald bugging President Johnson about UFOs, Johnson asked VP Humphrey's space technology advisor, Frank Rand, to make a quiet in-house study of UFOs to "get McDonald off my back". Rand actually liked the assignment and one of the first people he asked to be on this team was Art Lundahl. In another irrelevancy, in about 1968, Karl Pflock went to work for Lundahl. In 1970, Lundahl went to Dick Hall's home for an evening's discussion. The other "party guest" was Jim McDonald. [ McDonald had met with Lundahl many times previous, as he was asked to brief Frank Rand's team several times, without knowing what Rand et al were doing]. During the Hall-McDonald get-together, Lundahl said that he had talked to General Charles Cabell and the ex-USAF Intelligence chief, and number two in the NSA, continued to feel that UFOs "warranted attention". During the same get-together Lundahl said that he saw no reason why advanced technology couldn't be extremely small. He wondered aloud if a UFO might not be so small that "there might be one over there in that fireplace". McDonald said that Art's gist was that the "big ones we can live with, but these little ones get me." Regardless of how whimsical Lundahl might have been at that moment, the remark betrays a mind VERY interested in the UFO phenomenon. Lundahl retired from NPIC in 1973 due to severe arthritis. To my knowledge no one ever was able to read his UFO files (either at all or with enough time) to give us any real understanding of what was in them. (Mike Swords)
