From the article:
> In a stunning security breach that went largely unanswered, unidentified drones swarmed above the skies of America’s bomber base in Louisiana for days in March. Barksdale Air Force Base is home to B-52 bombers and nuclear weapons storage facilities, and command and control assets. According to ABC News, the drones arrived in organized waves of 12 to 15 at a time for hours each day for a week. This threat caused troops to shelter in place and the flight line to shut down.
Wow.
