Bob Dylan sang that the "answer is blowing in the wind."

But at Pine Grove Church in Casey County, Louisville, last week, a steel building was actually blowing in the wind. At least that's one of the only explanations locals can come up with for what transpired.

"I was kind of like everyone else - just awestricken," Casey County Sheriff's Deputy Freeman Luttrell said of the events.

Here's what happened: Luttrell was called to Pine Grove Church in the Elkhorn community to investigate a report that a 12-by-24-foot metal storage building weighing, about 4,000 pounds, was lifted approximately 30 feet into the air and dropped onto the church roof.

The mystery is that the sky that Monday afternoon was sunny and virtually clear - and the breeze had been calm all day.

"It was one of the prettiest days we'd had for a while," said Juanita Long, who lives up the road about a mile. "If it had been cloudy or something, you could think, 'Well, maybe it was a storm.' "

Between 2 and 3 p.m. Long heard two loud bangs, which she assumed to be a traffic accident at first. Upon hearing no sirens, however, she labeled the noise as possibly coming from farm equipment in nearby fields.

When she drove past the building a while later, she noticed damage to the church and saw guttering torn off. No longer 40 feet behind it, as usual, the small metal building was sitting next to the church.

There was a gaping hole in the church's vinyl siding about 20 feet above the ground, and evidence that the storage building had been slammed down on the roof, about 10 feet higher. Two hours earlier, the woman who cleans the church and her son, who was working in the churchyard, had seen nothing unusual. Their vehicle had been parked where the storage building landed.

Pastor Jeff Edwards said the locked general steel building, which had a few building supplies inside, contained no explosive materials, and no suspicious residues were found by the sheriff's office and state police.

The National Weather Service reported no strong winds or storms in the area, and there were no broken limbs or other evidence of wind damage nearby.

"They attributed it to a gust of wind," Edwards said. "I told people that in Acts Chapter 1, the Bible says that Jesus ascended and that the 120 were in the upper room praying. Acts Chapter 2 says the Holy Spirit came as a rushing, mighty wind, and it sealed those that were in the upper room praying."

Interestingly, the day before the incident, church attendance had been 120, and the hole in the church wall was in the prayer room, the pastor said.

Damage to this supposedly spiritual metal building has been estimated at nearly $20,000.
