Based on nothing more than a short clip of highly-zoomed video.
That these "experts" can make such a definite call, based on such limited data, calls into question the judgment of said experts.
The scariest part is that one of the so-called "experts" was a retired NORAD general. Thankfully he's not in charge now.
Jim Cash is a retired brigadier general U.S. Air Force. A former NORAD command director, former assistant director of operations at NORAD, a U.S.A.F. pilot of F-106s, F-4s, F-15s and F-16s for 25 years and the commander of an F-15 Squadron and an F-16 Wing.
If this guy's judgment is in question we'd better find out who's in charge of NORAD today.
