A relative has identified a mother and daughter who were injured when a small plane crashed while taking them to a California children's hospital so the daughter could have surgery.

Forty-nine-year-old Nancy Dellamaria of Redding and her daughter, 16-year-old Chloe King, remain hospitalized. There's no immediate word on their conditions.

Dellamaria's sister, Nancy Paquette, told the San Francisco Chronicle that the two were on board the single-engine plane that crashed Tuesday morning while trying to land at the Palo Alto airport. The crash killed the pilot, a man in his 60s. His name hasn't been released.

The plane was operated by Angel Flight West, a nonprofit group that provides free medical transportation. The volunteer pilot was flying the mother and daughter to Palo Alto because the girl had a surgery planned at Lucile Packard Children's Hospital.
