He was elected a Legacy Fellow of the American Astronomical Society in 2020. Interest in UFOs Sturrock has been a prominent contemporary scientist to express a keen interest in the subject of unidentified flying objects or UFOs. Sturrock's interest traces back to the early 1970s when, seeking someone experienced with both computers and astrophysics, he hired Jacques Vallee for a research project. Upon learning that Vallee had written several books about UFOs, Sturrock—previously uninterested in UFOs—felt a professional obligation to at least peruse Vallee's books. Though still largely sceptical, Sturrock's interest was piqued by Vallee's books. Sturrock then turned to the Condon Report (1969), the result of a two-year UFO research project that had been touted as the answer to the UFO question. Sturrock commented that, "The upshot of this was that, far from supporting Condon's conclusions [that there was nothing extraordinary about UFOs], I thought the evidence presented in the report suggested that something was going on that needed study." At about the same time that the Condon Committee was conducting its investigation, the American Institute of Aeronautics and Astronautics (AIAA) in 1967 had set up a subcommittee to bring the UFO phenomenon to the attention of serious scientists. In 1970 this subcommittee published a position paper also highly critical of how the Condon Committee had conducted its investigation and how Condon's written conclusions often didn’t match the cases detailed in the final report. Overall, the AIAA deemed about a third of the cases still unsolved. Unlike Condon, they felt these unsolved cases represented the essential core of the UFO problem and deserving of further scientific scrutiny. Sturrock was curious what the general attitudes of the members of the AIAA might be and in 1973 surveyed the San Francisco branch of the AIAA, with 423 out of 1175 members responding. Opinions were widespread as to whether UFOs were a scientifically significant problem. Most seemed unsure or neutral on the question. Sturrock was also curious as to whether fellow scientists like the AIAA members ever reported seeing UFOs, i.e., anomalous aerial phenomena that they couldn’t identify. The survey indicated that about 5% had, which is typical for what is usually reported for the general population as a whole. In 1975, Sturrock did
