A hot air balloon crashed into power lines in Clinton, Mass. late Saturday, burning five people on board in the resulting explosion. The balloon apparently struck the power lines while attempting to land.

The FAA confirmed to WBZ-TV in Boston, "A Colt Balloon was attempting to land in a residential area near Clinton, MA when it struck a power line and caught on fire today at 7:40 p.m."

Dennis MacDonald told the Worcester Telegram that his girlfriend saw the balloon hit the power lines from the front window of his home.

"She said, 'It's not going to clear those wires,'" MacDonald, said. "You could see the operator was trying to pump up the propane. It just didn't go up."
