These flight paths are indicative of many Cape Air flights that pass over Hull neighborhoods at dangerously low altitudes. The Cape Air pilot in the above image overflew the Allerton Hill section of Hull at 850 feet, the one below buzzed the same neighborhood at 825 feet. For those unfamiliar with Allerton Hill, there is a concrete fire control tower atop the hill with an elevation of 180 MSL. This puts Cape Air operating within 700 feet of an obstruction. Not only is this altitude unsafe for Hull residents, but it's also dangerous for the passengers on these aircraft.
On a number of occasions Cape Air has been in violation of FAR Part 91, section 119, paragraph 'b' pursuant to minimum clearances: "Over any congested area of a city or town, or settlement, or over any open air assembly of persons, an altitude of 1000 feet above the highest obstacle within a horizontal radius of 2000 feet of the aircraft shall be maintained."
There is an exemption to this rule for aircraft engaged in takeoffs and landings, however Allerton Hill is over 7 statute miles from Logan Airport. It is fair to say these aircraft are enroute at this point.
