"The 6-year-old boy who died was in the car with his two younger brothers, including an infant, and his parents, said Deborah Song, spokeswoman for Advocate Christ Medical Center in Oaklawn.
Their vehicle was crushed under the nose and fuselage of the plane, said Fire Department spokesman Larry Langford.
The mother, in her 30s, was in good condition; the father, in his 40s, was in serious condition; the 4-year-old middle son was in fair condition; and the infant was in serious condition, Song said.
Four people in the second car, which was under a wing of the Boeing 737-700 jet, were in serious but stable condition.
In addition, three passengers from the plane were in good condition, said Trotter, quoting paramedics.
