Before the Big Dig, traffic was so bad that for a short period of time, some Bostonians commuted by helicopter.
The New York Times reported on the helicopter service in an October, 15, 1989 article:
"Hub Express, which bills itself as the only Federally registered helicopter commuter airline in the nation, shuttles about 2,000 passengers a month between the main terminal at Logan and six heliports, five in the suburbs and one in the downtown financial district."
The service stopped in 1991.
