This factory's alleged haunting is the stuff of urban mythology, but who knows, it may be true all the same. As the story goes, a man who was crushed to death on the assembly line in 1944 sometimes shows up again. In one case, many years later, he appeared in the nick of time to save another worker from suffering the same fate.

In the 1950s, so the story goes, a supervisor was shot to death on the factory floor by an angry employee. Since then, workers report, when the living supervisors are on break, he often returns to the assembly line, shouting at the workers to keep things moving.

When this power generating plant was built in the late 1970s and early 1980s, a worker fell 100 ft. down an open elevator shaft in the Unit 2 reactor building. Workers say they frequently see the man standing on the spot from which he fell, and they report that there are many cold areas in this otherwise consistently warm building.

And at the Ford warehouse on Van Born Road in Romulus, things aren't much better than they are at the company's Detroit plant, according to various ghost-hunting websites. Located near Wayne Road, the industrial complex was originally owned by Stinson Aviation, which built planes there in the 1930s. The floor of one of the buildings is caved with the initials of several Stinson employees who called themselves "the left wing group." According to legend, the left wing of an airplane dislodged one day, killing several workers on the floor. The complex was later bought and expanded by Detroit Diesel, which operated it for many years, during which time a male worker committed suicide there. Now the Ford company uses the place as a storage warehouse. During both the day and night shifts, workers report hearing tools used when none are actually being operated and when things get quiet, there are sudden bouts of conversations between what they assume are past workers. Workers have also heard their names called out and had their backs tapped and their clothing tugged. They say carts move on their own, and sometimes strange men approach workers on the floor but then disappear as they get close. In the restrooms, workers say they have heard someone enter the neighboring stall, but when they look beneath the stall for feet, there is no one actually there.

Workers reportedly hear footsteps behind them, but when they turn around, no one is there. Things fall off shelves by themselves as workers walk down the aisles. And a mysterious presence is felt, sometimes announcing itself in a creepy voice that comes from everywhere at once.

It's hard to know what's scariest about this story: the ghost or two of its observers' cowardice. On Feb. 20, 2004, phone technicians were working after hours to install new phone lines into a phone closet in one of the manufacturing buildings. They were a team of three: two men and a woman. Next to the phone closet was a door, behind which the team heard repeated noises. Finally the woman opened the door to find the ghost of a little girl holding her arms out to be picked up. The woman was so startled, she jumped backwards, falling into the men. When the men saw what the commotion was about, they took off, carrying the team's only two flashlights, and hightailed it out of the building. The woman was left alone in complete darkness, as the power had been turned off, to find her way out of the building, but finally made it to an exit where she found security waiting. The team refused ever to return to finish the job. One can only hope the woman refused to work with her teammates ever again as well.

Although we weren't able to confirm this by press time, the story goes that the original founder's wife and son were shot execution style on the premises. Today, they are seen by both workers and security guards on the night shift, wandering through the factory. The woman wears a white dress, and the boy plays and runs. Since children are not allowed on the premises, newbie workers are often shocked the first time they find the child there, and even more shocked to discover that the child is a ghost.

This plant was built over a Native American burial ground, and workers have reported hearing war cries as well as gunshots, as well as feeling a powerful surge of energy from an unknown presence. One worker even claims to have suffered a powerful blow to the chest from an invisible force, which left a scar.

Second- and third-shift workers claim to have seen ghosts dressed in clothes from bygone eras. Running footsteps and screams are also heard late at night.

Back in the 1970s, so the story goes, a boy disappeared into the woods behind the plant, never to be found. Today, workers report hearing him crying, along with leaves rustling and branches breaking, but when they explore the area, there's never anyone there.

Back during the days of Prohibition, this oddly-shaped building was a speakeasy. One of the hostesses, who was married to a seaman, had an affair with the piano player, and when her husband returned from a trip to Alaska, he found out and shot her dead on the beach below. Today she remains there, known as the Blue Lady due to the color of her dress. She is known to be a very friendly ghost who's fond of pranks.

At the power plant that was originally built in the 1880s on Harbor Drive near the airport as well as Kearny Mesa on Ruffin Road, solar turbines now stand. In the engineering factory areas, ghosts of devoted workers from other ages are frequently seen. And in the offices, unintelligible whispers are heard, elevators operate on their own and doors swing open and shut by themselves.
