Notes from Penobscot Island Air: The original air service was established in the late-1940s by Arthur Harjula with a single J3 cub. It was later named Stonington Flying Service when purchased by Herb Jones. When Herb's son, Charlie, took the business over he renamed it Penobscot Air. In the early-1990s, Clint and Hannah Demmons bought the air service, retaining its name. In 1999, they sold to the Telford Group. In 2003, the Telford Group established the air service as Maine Atlantic Aviation. In 2004, the division was purchased by another individual, who retained the name Maine Atlantic Aviation.
