Transcript for Parasailing Crash Survivor Recalls Horrific Accident
Lots of us plan our vacations by thrill seeking adventures. But carefree adventures can turn dangerous. Fast. Tonight, a teen survivor speaks out for the first time since her horrifying accident was captured on video. ABC's Matt Gutman brings us her incredible survival story. Reporter: It started off as an adventure. I was videotaping them and taking pictures. You can see them down here. Reporter: 18-year-old Sidney Goode and her friend Alexis Fairchild parasailing in Panama City, Florida. You just assume that everything is safe. They tell you, they advertise it, safe, fun. You expect that. Reporter: Fun. That's what parasailing is supposed to be, a recreational sport that gently lofts you up 500 feet over the water. But for them, the serenity of flying like a bird turns terrifying. Watch as the unthinkable happens 13 minutes into their adventure. It was really bad, the feeling of the wind. Like that feeling was terrible. Reporter: After winds gust, the cable attaching the parasail to the boat snaps, flinging the dpirls headlong into this 13-story building. They're at the commodore and a parasail just smashed into the top of it. Reporter: People on the balconies tried desperately to hold on to the girls to keep them from flying away. I remember flying into the building. The only thing I felt was the people's arms grab me. And then I woke up in the hospital bed with a breathing tube in. Reporter: Were you guys screaming while flying through the air? Oh, yeah. Obviously no one could have done anything at that point. Reporter: Bouncing off the condo and over it, they careened into power lines, crashing down onto this parked SUV, where paramedics and Sidney's father found them. Could you tell that she was alive? No. They were bagging her. I didn't know if she was alive or not. Reporter: In critical condition, both teens were rushed to the hospital. Once there, doctors knew they only had moments. Sidney was hooked up to a ventilator, undergoing emergency brain surgery. Even if you think that she's going to wake up and come out and breathe on her own, we didn't know if she could walk or talk. They told us she may not remember. Reporter: But eight days after the accident, Sidney finally came to. When I woke up and said that, because I had just gotten off my breathing tube, I had no idea. It just amazes me how that happened to me and I can't remember it. Reporter: And now, one year hater, for the very first time, Sidney is sharing her story with us on that very same beach where she came so close to death. I think about it constantly. I have reminders of it, my scars, everything reminding me of it. And everybody always brings it up to me. Reporter: But Sidney and Alexis' ordeal is not isolated. Over the past 30 years, 429 people have been seriously injuring parasailing in the U.S. 73 have died. Turns out, the equipment used in parasailing is not required to be inspected by any government agency. That includes the tow lines and the harness. No agency performs any kind of mandatory inspections on the safety equipment. It's been left up to each individual operator to define safety as they see fit without repercussi repercussions. Yesterday, the national safety transportation board issued a stinging rebuke of the parasailing industry, accusing operators of poor judgment, lack of experience and improper training. Now they can only recommend that all operators be licensed by the coast guard, which doesn't sit well with Sidney's mom. So when the ntsb calls for more regulations but can't enforce them, how does that make you sneel It makes me sick. Reporter: The w59er sports association industry says it was weather and not faulty equipment that caused the accident. Yesterday, Sidney and her parents visited the hospital and the very doctors who had saved her life. Thank you. You look great. Reporter: What did she look like when shep first stepped in here? Oh. You look wonderful today. Reporter: The team worked day after day keep Sidney alive and her friend, Alexis. What makes you cry when you think about it? Everything. It just amazes me that I'm here to walk and talk to them. When they walk in like this, it makes everything worth it. Reporter: The girls have a long road ahead of them. Both still suffer from brain damage according to the lawyer. Sidney's friend, Alexis, now reads at a third to fourth grade Reading level and Sidney at a fifth to sixth grade level. Both had titanium plates and screws inserted in their heads for multiple facial fractures and they have endured damaged optic nerves. And Sidney had little recollection of the doctors who took care of her for weeks on end. Sidney, how are you doing? Good. I don't recognize you. You probably don't remember any of this. We saved your life. Well, thank you. I'll give you a hug. Reporter: But Sidney did remember one doctor, Rebecca, who promised Sidney she would walk again. You're so brave and strong. You can do anything, right? And you have. Reporter: And that she did. At her high school graduation, just shy of year after nearly dying on that beach. Flashing that sunshine smile. For "Nightline," I'm Matt Gutman in Panama City beach, Florida.
