https://www.wsj.com/politics/nationa...02ffc8?mod=mhpThe use of helicopters around Washington has become so frequent that the sound of the whirling blades has become ubiquitous at the Pentagon. Defense officials can look out their windows daily and see them landing and taking off, sometimes in pairs.
Army helicopters sometimes ferry three-star and four-star generals from Fort Belvoir to the Pentagon, shaving 45 minutes or more off a trip by car, said Andrew Logan, a Washington resident who co-founded Helicopters of DC, a website that tracks helicopter operations.
The Air Force’s 1st Helicopter Squadron, based at Joint Base Andrews in Maryland, also has responsibility for ferrying senior government officials and VIPs around Washington, a mission its pilots sometimes discuss, Logan said.
