When your kids hop into a bouncy castle for high-flying fun, the last thing you want to think about is whether they're climbing directly into the path of danger. But that's exactly what happened for the families you are about to meet who found themselves shaken up in all the wrong ways after a carefree afternoon gone wrong. Here's ABC's gio Benitez. Oh, my god! Reporter: All it took was a gust of wind to turn this blow-up slide into a bucking bronco andsparking -- panic from parents watching in horror. But there were, two kids in fact. An 11-year-old and a 12-year-old. It was complete terror. I had no idea what to think. Reporter: The families say they were at this lacrosse tournament, the blowup slide all part of the fun and games until -- We have an emergency. The bouncy castle blew over and some kids fell out. As I got closer I could see that there was a body laying on the ground. And the reality hit me that, that oh, my gosh it was my daughter that was on the bouncy house. Reporter: Madison fell off almost immediately. I landed. Then I went back up. I started screaming. Reporter: But A.J. Was trapped inside. Violently turned and turned along with the slide for 300 feet. I like was picked up into the air. I hit -- one of the slide, then I hit the back of it. I was just thrown around ape lot. I couldn't get a grip on anything. By the time I hit the ground I pretty much just blacked out. I pretty much hit my head. They were holding his neck. Trying to keep him calm and still. Reporter: Incredibly, A.J. And Madison's injuries were minor. I think we were just very blessed. I could have died from this. I am very, very happy that I am okay. The owner of airbound, the company operating the slide involved in this weekend's incident tells ABC news "We terrible for what happened. Safety is our number one concern. Adding that the slide was properly staked. At 18 miles an hour you need to shut it down. Deflate it. Winds hatch caused bouncy nibt mare nightmares before. Two children were injured when a gust of went sent this bounce house sailing. And 13 people were sent to the hospital after this 2011 bouncy slide accident in Long Island. Oh, my god. But as modern family's Manny knows all to well. Bouncy houses don't have to take flight to be dangerous. Be right back. Reporter: Safety experts say this is not the time for a laugh track. If this was a disease that would be an epidemic. Reporter: In 1995, there were 702 injuries from inflatable bouncers. By 2010 it skyrocketed to over 11,000 injuries per year. The two biggest causes of injury are when children are inside rough housing and bump into each other. And when they fall out of the bouncy house. If you want to -- Reporter: Mark Rolland who owns and operates the rides agrees there is a problem. I just think it needs to be controlled. And there needs to be more regulations. Reporter: Setting up a bouncy castle and making sure it doesn't fly away is no kids' game. Sometimes people tend to get a little lazy when setting pieces of equipment up. They tend to leave the tether line here and place the sandbag on top like that. If you've didn't have the sandbags this is what you would be using. You would get the steak putting it in the ground. We drive these into the ground with a sledgehammer. Reporter: The whole point is to hold the ride down. And itch there are high wind, like that gust over the weekend, everybody gets out. We had to crawl. Reporter: Mark takes us inside and insists kids need to be careful too. And operators outside should be watching. If you had a child laying down and three other children bouncing around, there is -- a great potential for an accident to happen. Reporter: And he says, not all bouncy houses are created equal. Here we have emergency escapes here in case this thing were to deflate. Correct. Reporter: A lot of bounce houses they don't have that. A lot don't. Some do. Reporter: In this case, there are ways to keep kids from just falling out. This is a small exit. It's a little safer. Because it is stopping the children from just coming out, if the whole thing was, open. This may surprise you, but this industry vet believes in tighter restrictions. Too many people are being weekend warriors with these units. Not caring or not understanding what the safety requirements are. Reporter: Some lawmakers and parents agree. The families say they hope telling their story will spark action. The last thing I want to see is another kid go through this. Reporter: For "Nightline,"
