Dr. Eric W. Davis, formerly a contract research physicist at NASA's Breakthrough Propulsion Project which ran from 1996 through to 2002, gave a lecture in 2010 where he responded to the question of UFOs as they pertain to potential physics for traversable wormholes, warp drives, and anti-gravity. Sponsored by the Society for Scientific Exploration, the lecture was about a then recently published book, Frontiers of Propulsion Science, regarding discoveries from the NASA project. After the lecture, during a question and answer session, one questioner asked whether, "...properties of UFOs had guided the thinking and research of that initiative." In responding to the question, Dr. Davis said, "Secretly yes and overtly no."

In giving a reason for the secrecy, he stated that, "UFOs don't have credibility with mainstream academic researchers," and that, "...policy makers and decision-makers in charge of funding and programatics ... don't want to hear the topic of UFOs. So, for the purpose of doing this officially, [we didn't bring in UFOs], but we did consider it under the table."
