Well, <i>that's</i> unexpected!<p>The Utah footage is at least consistent with human aircraft behavior. Could be a high-altitude drone (if it's silent, it probably isn't a helicopter) or perhaps an airship.<p>The Israel footage... well. You could definitely fake that with an hour in an editor. On the other hand, a flash like that should have attracted a shitload of eyewitnesses... so, there ought to be tons of corroborating reports.
