UPDATE: The Notice to Air Missions (NOTAM) that was established over Lake Michigan appears to have been pulled, according to multiple sources.

It is still unclear what the original NOTAM was for, but there currently still appear to be planes in the area.

The NOTAM was originally put in place for “national defense” reasons, although those reasons were never specified.


Original Story

The U.S. has just announced that the airspace is being shut down over Lake Michigan for “national defense” reasons.

This follows the shutting down airspace temporarily over Montana last night after a reported “object” or anomaly was spotted over the area. They said they were going to continue to monitor. This is maybe an indication that they’ve now picked the object up again further along its path into the U.S. or it may be another one.

There are unconfirmed reports of fighter jets being scrambled, but that would be logical given the situation.
