Los Angeles ? A 12-year-old girl who was the sole survivor of a plane crash in Panama is “doing quite well” following her return to California, while dealing with the devastating loss of her close friend, her mother said Tuesday.

Francesca Lewis of Santa Barbara has been resting and going on short outings since her return Friday night with her parents, her mother, Valerie Lewis, told The Associated Press.

Francesca remembers little about the Dec. 23 crash that killed her friend, Talia Klein, 13; Klein’s father, Michael Klein, 37, a prominent businessman from Santa Barbara; and Panamanian pilot Edwin Lasso, 23.

Francesca was on vacation with the Kleins when their Cessna 172 went down.
