The explanation given is that cartel air drones entered US airspace.

I guess my question is, doesn't this happen all the time? I would think drones would be an easy way to fly a Kilo over the border to whatever dropspot you wanted. I wonder what the new wrinkle is?

Will be interesting when/if more information is released. I am not sure why folks are so surprised or think it’s shocking. While definitely out of the norm, my mind was immediately thinking 10 days seems like an even number where you are trying to find or do something, not sure how long it’s going to take so you just stick it. Certainly odd that it’s only a few hours but for all I know there is some written government procedure for whoever is doing that sets it at 10 days.

So bizarre

Why the 10 day announcement overnight only to totally rescind it before the majority of US citizens wake up and read the news?

don't attribute to security concerns...what can be explained by incompetence...

WTF? The FAA announces a ban on all flights at an international airport and then withdraws the ban within a few hours of the announcement? What kind of insane police state would try a stunt like that? Even for the Trump administration, that is setting the bar at a new low.
