HEADS UP! BLACKHAWK HELICOPTERS ARE SWARMING DOWNTOWN BOSTON IN SECRETIVE DRILL
For several days this week, people in Boston and the surrounding area have heard large helicopters flying around the area.
Many people reached out with concerns that the helicopters were passing very close to buildings.
The Blackhawk helicopters were all lined up on the tarmac at a local airfield Wednesday. The Department of Defense would not comment on the exercise.
The exercise is expected to continue until Friday.
