Are the spirits of past heroes still on duty aboard the World War II-era aircraft carrier Yorktown at Patriots Point?

Tune in at 9 p.m. Wednesday on SyFy Channel’s “Ghost Hunters” to find out.

A crew from The Atlantic Paranormal Society spent several nights in early February onboard the docked museum in Mount Pleasant when it was closed to the public and didn’t have power following the return of the warship Laffey.

“Over the years, we have received a number of reports of unexplainable noise, sightings and activities from visitors to our ship, employees and area law enforcement officers,” said Patriots Point Executive Director Mac Burdette. “I can’t divulge whether or not TAPS found anything, but I can tell you that their staff said their visit provided some of the most compelling evidence they’ve seen in the history of the program.”
