This is either Arlene Payan's worst day ever, or her best:
JACKSONVILLE, FL -- Her hands still trembling, her clothes and hair still damp, Arlene Payan found the strength to talk about the drop that could've taken her life.
"It's scary, it's nothing fun," she said.
A blown tire forced her to stop on the bridge.
"There was a huge rock on the bridge," said Arlene. And I got off the passenger side to check it out. And that's when I heard the screeching when the other car, a Hummer, hit the side of my car."
The H2 Hummer smashed into her little Toyota.
The force sent Arlene's car into her.
She sailed over the railing.
"After that, I just remember when I was flying over the bridge," she recalled. "I don't know how the car hit me or anything."
She popped up like a cork, twenty feet below, unhurt.
"I just started swimming, I had to. I just started swimming and just hoped everything was going to be OK."
A Jacksonville Sheriff's Officer leapt from a helicopter hovering over the river and hauled her to a boat.
"It was wonderful. I'm glad they were there."
Back on dry land, Arlene refused a ride to the hospital and came back to check on her car.
She works as a manager at a pharmacy in Jacksonville Beach. Her boss gave her the day off.
