FoxNews is reporting that Pentagon spokesman Col. Dave Lapan said he is not able to concur with an official from North American Aerospace Defense Command/U.S. Northern Command who told Fox News earlier that there was "no threat to the homeland."
Lapan said the military doesn't know exactly what the so-called mystery missile was so can't say it's harmless.
Lapan said it does not appear that whatever was flying was part of a "regularly scheduled missile test." He noted that before a missile test, notifications are sent to mariners and airmen. This does not appear to be the case here.
