PORTLAND, Maine (AP)  A New Hampshire-based helicopter service has begun its expansion into Portland, Maine.

Seacoast Helicopters began service to Portland this week, offering tours of the city’s historic downtown, Casco Bay islands, and lighthouses around Portland.

Bruce Cultrera, president and CEO, said the service is starting with one helicopter at the Portland International Jetport. More helicopters will be brought in, if needed.

The service started with a single pilot and a single helicopter at the Pease International Tradeport, but now has six helicopters and nine pilots.
