Navy pilots saw something real: NASA chief orders probe into UFO sightings
NASA chief Bill Nelson has ordered the space agency to investigate the recent UFO sightings. "I've talked to those Navy pilots and they're sure they saw something real," said Nelson. "We don't know if it's extra-terrestrial, we don't know if it's an enemy. We don't know if it's an optical phenomenon," added Nelson, while dismissing the possibility of an illusion.
