The big story here in Houston is that the public has been shocked by helicopters flying as low as 150' at 80 mph yesterday. I saw one go between two buildings yesterday downtown which I have never seen before. The mission is somewhat secret, but apparently they are measuring a baseline for natural radiation so that they can scan again on SuperBowl Sunday and locate unusual radiation. I didn't check any of the apps or web pages but I was wondering if the FAA warned drone owners. Seems like there could have been an issue. I know there's a huge no fly zone on Sunday.
