An international rescue effort was launched Thursday for a 16-year-old girl trying to sail solo around the world.
Abby Sunderland was feared to be in trouble after her emergency beacons were activated overnight and there was a loss of communication.
She's believed to be in the southern Indian Ocean between Africa and Australia. The vast search area will mean long hours for the rescue teams, but members of Sunderland's family are confident she's alive.
"She's got all the skills she needs to take care of what she has to take care of. She has all the equipment as well," her brother Zac -- who sailed solo around the world at age 17 -- said.
Australian Maritime Safety Authority spokeswoman Carly Lusk verified three vessels and an airplane were headed to Abby's location.
Qantas airlines said in a statement that an Airbus A330 tasked by the safety authority took off at 7:53 a.m. Friday Perth time.
Two emergency beacons were continuing to broadcast and location data showed they were together and drifting at 1 mph.
Abby left on her journey in January and was halfway finished.
