In an interview with CNN, newly-minted NASA administrator Bill Nelson chimed in on the topic of UFOs ahead of the release of a long-awaited report on the strange sightings.

“Well, I have talked to those Navy pilots, and they are sure that they saw something,” Nelson told CNN. “And of course we’ve seen their video from their jets.”

But despite having been briefed on the forthcoming report “in my capacity on the Senate Armed Services Committee,” Nelson mostly reiterated the same questions we’ve heard over and over — perhaps a hint that the unclassified version of the report will offer little in terms of new explanations for the mysterious phenomena.

“We don’t know if it’s extraterrestrial,” Nelson told CNN. “We don’t know if it’s an enemy. We don’t know if it’s an optical phenomenon. We don’t think it’s an optical phenomenon because of the characteristics that those Navy jet pilots described.”
