Excerpt:

ALAMEDA -- Not long after she began working as education manager on the USS Hornet, Heidi Schave found herself alone on the retired aircraft carrier and floating museum.

"It was an admin holiday and no one had told me," she said.

That was unsettling realization No. 1. Unsettling realization No. 2: She wasn't really alone.

Schave was sitting in her office, she said, when "it got really cold. I saw a man in a blue uniform. He was clear as day, like you or I, but he wasn't making any eye contact. He was sort of slow moving. There was a bulkhead there, and he walked right through the bulkhead."

Schave is certain she saw one of the spirits that make the Hornet a bucket-list destination for those interested in paranormal activity. And, those enthusiasts claim, a post-bucket-list destination for apparitions.
