When you're born on an airplane in mid-flight, where do you say you were born?

A seven-pound, eight-ounce girl was born Wednesday night on a Mexicana Airlines flight from Guadalajara, Mexico, to Chicago's O'Hare International Airport. An airport spokeswoman says the baby was born nearly an hour before the plane landed.

Luckily for mom and baby, there was an obstetrician on board.

The 42-year-old mother was traveling with her husband and two other children to visit relatives in Milwaukee.

A hospital spokeswoman says mother and daughter are doing fine.
