A 16-year-old girl has survived after plummeting more than 915m to the ground in a skydiving accident in the US.
Dr Jeffrey Bender, a trauma surgeon at the University of Oklahoma Medical Center, says Makenzie Wethington is recovering after the jump where she hurt her liver and broke her pelvis, lumbar spine in her lower back, a shoulder blade and several ribs in Saturday's fall. She also has a broken tooth.
"I don't know the particulars of the accident, as I wasn't there. But if she truly fell 3000 feet, I have no idea how she survived," Dr Bender told reporters.
Makenzie was in a good condition and was expected to leave the intensive care unit.
On Saturday, before her skydiving adventure, the teen wrote on her Twitter account: "Me: Why am I the only girl doing this? My dad: You're the only girl who has balls."
She tweeted that she would be jumping with her dad.
Her parents let her jump, but her father, Joe, now says the skydiving company shouldn't have allowed it.
Nancy Koreen, director of sport promotion at the US Parachute Association, said its safety requirements allow someone who is 16 to make a dive with parental consent, though some places set the age higher.
Robert Swainson, the owner and chief instructor at Pegasus Air Sports Center in Oklahoma, defended the company, saying the father went up with his daughter and was the first to jump.
Mr Swainson said Makenzie's parachute opened OK, but she started to spiral down when the chute went up but not out.
He said divers were given instructions during a six- to seven-hour training session on how to deal with such problems.
Mr Swainson said Makenzie had a radio hookup in her helmet through which someone gave her instructions.
"It was correctable, but corrective action didn't appear to have been taken," he said.
Mr Swainson said he did not jump out to help Makenzie because there was no way he could have reached her, and another jumper got scared and refused to make the jump.
"The most I could have done is screamed," he said.
