Note: This is Part Two of a four-part miniseries.

On Tuesday morning, August 30, Medea Gabriel looked out the sixth floor window of Memorial Medical Center in New Orleans. She was a nurse in the neonatal intensive care unit, the NICU. The hospital was surrounded by water, for as far as she could see.

The babies in the NICU had to evacuated by helicopter, to a hospital in Baton Rouge, Louisiana. And she had make sure that her babies would be prepared to survive the trip. And then, once they were gone, that her ailing mother could be transported to safety.
