So our mystery Drink-and-Droner has been revealed.
According to the New York Times, the guy who, yesterday morning, caused a huge ruckus by crash-landing a drone on White House lawn and testing the limits of the Secret Service's abilites at 3am, has been revealed to be an officer with the National Geospatial Intelligence Agency. Apparently, he was enjoying some adult beverages on his apartment balcony and playing with a drone that "belonged to a friend" when it miiiiiiight have flown over the White House. He later admitted the dalliance to authorities - after his friends told him about the news story - though it does not appear he asked for his drone back.
It was 42 degrees, lightly raining and pitch black near the White House when an inebriated, off-duty employee for a government intelligence agency decided it was a good time to test-fly his friend’s quadcopter drone that sells for hundreds of dollars and is popular among hobbyists.
