UFOs are very real, as we have recently seen — but that doesn't mean E.T. The Navy pilots said some UFOs reached hypersonic speeds without any detectable exhaust plumes, suggesting the possible involvement of super-advanced propulsion technology. There are multiple possible prosaic explanations for the Navy pilots' observations, said Seth Shostak, a senior astronomer at the SETI ( Search for Extraterrestrial Intelligence ) Institute in Mountain View, California. He also noted that, according to the recent Times story, the Navy pilots began spotting the UFOs after their jets' radar system was upgraded. "If the aliens are here, you gotta say they're the best houseguests ever, because they never do anything," Shostak said.
