For some time, expressing interest in unidentified flying objects, or UFOs, has been deemed mostly unacceptable in wider society. But attitudes appear to be changing in America this week, with luminaries from Barack Obama to the former NBA star Shaquille O'Neal sharing their thoughts. Obama was asked about the issue of UFOs during an interview. Much of the newfound, and newly sincere, interest in UFOs, this week appears to stem from a report on CBS's 60 Minutes on Sunday, which tackled "the US government's grudging acknowledgment" of UFOs. With the defense department and intelligence agencies due to deliver a much-anticipated official report on mysterious aerial sightings next month, 60 Minutes interviewed a number of credible witnesses, including a former navy pilot who said he had seen unidentified aerial phenomena " the government's preferred term " "every day for at least a couple years". That prompted Obama's discussion of aerial phenomena. "What is true, and I'm actually being serious here, is that there's footage and records of objects in the skies, that we don't know exactly what they are, we can't explain how they moved, their trajectory," Obama told CBS. "They did not have an easily explainable pattern. And so, you know I think that people still take seriously trying to investigate and figure out what that is. But I have nothing to report to you today." On Monday, O'Neal shared his experience of seeing a "flying saucer" with ABC.
