Helicopters to be Used for Aerial Patrols

Merrimack Police issued an alert on Sunday informing residents not to be surprised if they see helicopters buzzing about the skies in Merrimack in the middle of the week.

According to the alert, Public Service of New Hampshire will be conducting maintenance flyovers along transmissions lines as part of an aerial patrol for vegetation maintenance.

"These visual inspections are important for electrical system reliability, and are not being conducted for the Northern Pass Project," according to PSNH.

Working in concert with JBI Helicopters, and assuming weather conditions permit, the patrols will occur April 9 through 11 between 8 a.m. and 3:30 p.m. They are being conducted all around New Hampshire.
