"I was really scared," she continued. "So I started yelling for help. I was thinking, 'Am I going to die out here or is someone going to find me?'"
"I could hear someone looking for me, and they were running for me, and I like saw them come to me, and I just felt relief," she said. "Felt like God answered my prayer."
Wells was rushed by ambulance to the hospital, where Stephanie Younger had just learned about the crash.
"We overheard someone say that the helicopter crashed," she said. "And the only person [who] came in was Jordan. And to hear it like that, it was, you know, it was still hard to believe [her daughter Ashley] was gone."
At 4 a.m., Scott and Lynn Wells received a phone call informing them of the accident.
"We went to the emergency room, and I knew something different was up because the head doctor was right there, and he's saying things like, 'You know, your daughter was the sole survivor of a helicopter crash,'" Scott Wells said.
Dirt and helicopter fragments were embedded deep into Jordan Wells' body. She had sustained several serious injuries, and her legs were completely shattered, a bloody mangle of muscle, bone and skin.
"We just put our hands on her and prayed for her," Scott Wells told "20/20."
After several hours of surgery, Wells was transferred to the Baltimore Shock Trauma Center. For 10 days, doctors operated to put her back together. They fought to contain the infection in Jordan Wells' right leg, but it was a losing battle.
"I remember waking up in the morning in the hospital and seeing my pinkie toe was gone and then my next toe was gone," she told "20/20." "Every time I went into surgery they took a little piece off my foot. [And] my doctor told me how it was going to be if I kept it and it would be infected. And he told me the best thing to do is to amputate."
When she finally came home from the trauma center two months later, it was "fantastic" for her parents.
"Her friends arranged a reception for her," Scott Wells said. "They were sitting in front of the house with a banner, screaming and yelling and videotaping and just welcoming her home."
When she first arrived home, Wells required around-the-clock care. A parade of visitors and friends were always around, lending a hand ... and a laugh. But her recovery was slow and painful; she was almost totally dependent on her parents.
"I think it's pretty tough, because my mom has to stay by my side for everything," Wells told "20/20."
Wells was confined to a wheelchair but made tremendous progress, eventually taking part in a swimming competition and going horseback riding.
In February, Wells attended a National Transportation Safety Board hearing in Washington investigating her crash and others involving medevac helicopters.
Preliminary findings suggest that the emergency chopper should have stayed on the ground that stormy night. Air traffic controllers, the report says, were "casual and sloppy," relaying a misleading weather report to the pilot that sent him straight into thick, blinding fog.
For families of the dead, questions linger about why the girls were airlifted instead of sent by ambulance to the hospital, questions, of course, that will never bring back Ashley Younger.
