Other generations of the Starship Enterprise have fallen to Romulans, renegade Klingons, even to one of its most illustrious captains, James T. Kirk.

Now a current-day version of the “Star Trek” flagship faces an attack less dramatic but no less deadly. The foe is creeping mold overrunning its current docking area, an abandoned government building on the north side of Bangor International Airport.

The crew that built this wooden replica of the Enterprise bridge is the U.S.S. Kasimar, an organization of 85 science and science fiction enthusiasts. Over the past 15 years, the bridge has served as a draw for fund raising by local charitable groups, and the Kasimar’s members have volunteered their efforts to charitable causes as well, helping to raise thousands of dollars.

“The man-hours this organization has put in [volunteering] over the last 15 years is staggering,” said Susan Libby, the Kasimar’s chief administrative officer and wife of Kasimar Admiral Mark Libby. “We’re still trying to figure out the [exact] amount of money we’ve raised.”

Now the Kasimar needs the community’s help, as they must find a new home for the Enterprise bridge before the mold overtakes it.

Its current home is a flat-roofed government building, which the bridge was moved into in the summer of 1998. The structure, a former bomb shelter, was badly damaged during the ice storm of 1998, but that storm’s insidious effects took some time to reach the back end of the building where the Kasimar got permission to set up shop. The General Electric expansion is taking place next door.

Libby, armed with a flashlight, leads the way through the derelict, past fallen ceiling tiles, squishy swatches of carpeting and empty offices. She yanks on a chair to open the rear door, to let some light into the powerless building. The looming bridge, 9 feet tall and 37 feet by 40 feet, is protected by blue plastic sheeting. A pile of items awaits an upcoming garage sale, while computer equipment sits ready to be installed into the bridge.

“We used to hold monthly meetings here, but we can’t meet here anymore, because the air quality is so bad and some of our members have asthma or allergies,” Susan Libby explained. “With the GE expansion, sometimes we can’t even get into our door.”

The money raised by the not-for-profit organization goes either to charity or into upgrades for the bridge, so there’s no funds left over for rent, Libby said.

The bridge was originally constructed by more than 40 vocational students in late 1985 and early 1986, with funding for the wooden superstructure provided by the Bangor Daily News and the Bangor State Fair. It was then transported in two 40-foot moving vans to the abandoned Sears building on Harlow Street.

There, over the next 45 days, the crew of the Kasimar transformed that wooden structure into a replica of the Enterprise bridge, working long hours with donated supplies. The bridge had to be movable, so that meant that all the detail work had to be removable. The captain’s chair had to be durable, to withstand its many visitors to come. The rear axle of a Caterpillar tractor with a sheet metal base was used as the chair’s swivel.

The bridge made its first appearance at the 1986 Bangor State Fair. It’s been transported to Pittsfield for the Egg Festival and to St. John, New Brunswick, for a fund-raiser for the Children’s Wish Fund. It was a highlight of Bangor’s first science-fiction convention at the Civic Center in 1991.

Among the groups the bridge and the Kasimar have helped are the Ronald McDonald House, United Cerebral Palsy, the Make a Wish Foundation, the Bangor animal shelter, the Bangor homeless shelter, Northeast Combat, the Salvation Army and the American Red Cross.

The bridge was first housed at a garage at Bass Park, then a hanger on the south side of the airport, before moving to its present location.

“We’re fortunate to have this building,” Libby said. “But [the bridge] is a wooden structure, and the mold is just going to eat it.”

An ideal space would be about 60 feet by 60 feet, Libby said.

“We’d love to have a place to set it up, keep it up, and work on it,” she said. “We’d like to use these computers to make it more interactive.”
