It's all over the news.  But what I'm thinking that none of the reports I have read mentioned is that whether it was an accidental or deliberate intrusion, this little “exercise“ gives our enemies a view of evacuation pathes and emergency responses.  Government leaders may be more vulnerable while responding to a real or imagined threat from the air when the real and greater threat could be from the ground.  I'm not sure I would want to be in the “main herd” during such an evacuation.
