KITTERY — A planning board has failed to approve a proposal for a park in honor of the men who died aboard the USS Thresher submarine, which sank 220 miles off of Cape Cod 50 years ago.

The planning board in Kittery, Maine, had concerns Thursday night about the proposal, ranging from a lack of parking to the actual presentation; members said the type was too small.

The Portsmouth Herald reports (http://bit.ly/YyCD0x) the Thresher Memorial Project Group hoped to break ground soon on the park adjacent to Town Hall, to include a “circle of honor” to recognize the 129 men who perished aboard the submarine. Work also would take place at the Memorial Circle, with a granite base installed around the flagpole.

A motion to approve the plan as presented failed 3-3.
