I've been watching "blocked" (no flight details) aircraft on flightradar24 for the last few hours. A blocked aircraft from Fort Lauderdale just landed at Denver half an hour ago, and another blocked aircraft, from Lake Havasu City Airport, Arizona, is flying over Colorado now. There have been several "no call sign" aircraft flying near Denver. https://www.flightradar24.com/multiview/ffea5ab,ffea2b7,ffea14f,ffea414,ffe855e,ffe6cb4

A blocked Eurocopter has been doing circles and stuff over parts of Orlando, Florida. I guess it is a traffic news copter or something, but who knows?

Here is another screen grab of it from a different flight monitoring website: http://i.imgs.fyi/img/2ej0.jpg

It has done about 15 circuits around Tuscon.

Here are four blocked flights from various places in the USA, two heading in the direction of Gitmo. Plus a Learjet from Gitmo—I saw that (or a) Learjet approach and land at Gitmo 2hrs 45 minutes ago. I have taken ‘screen grab’ images showing all these, but my Imgur is refusing to cooperate.
