One bounce. One bad landing. One broken neck. That is all it takes for a family in Nolanville to have their lives altered forever.

You might be at the hospital right now, sitting in a waiting room chair at McLane Children’s in Temple or a trauma center in the Killeen-Nolanville corridor, watching your child sleep through a haze of pain medication. You are replaying the moment in your head: the sound of a bone snapping or the sight of your child disappearing into a foam pit and not coming back up. You remember the hand on the kiosk at the front desk, clicking through 20 screens of a waiver you didn’t have time to read because the line was long and the kids were excited.

We have spent twenty-five years standing at those same bedsides. We have represented families whose children arrived in those trauma bays with comminuted femoral shaft fractures, traumatic brain injuries, and spinal cord damage. What we have learned over those two decades—and what every parent in Nolanville needs to hear—is this: what happened to your child was not an accident.

A trampoline injury is almost always the predictable output of a business decision. When a park in Bell County staffs its courts at half the required ratio to protect its bottom line, or when a manufacturer like Jumpking or Skywalker sells a backyard trampoline they know the medical community has warned against for 25 years, they are making a choice. They are choosing margin over your child’s growth plates. They are choosing efficiency over your child’s spine.

Attorney911 was built to make corporate defendants answer for those choices. From our base in Texas, managing partner Ralph Manginello and our legal team handle catastrophic trampoline injuries in Nolanville and across the country. We don’t handle these like “slip and fall” cases. We handle them like corporate accountability battles. Our team includes Lupe Peña, an attorney who used to sit on the other side of the table—defending the very insurance companies and trampoline parks we now sue. He knows which waiver clauses are airtight and which ones are full of holes. He wrote the playbook; now we use it to win.

If your child’s life changed in a single jump at a facility serving Nolanville, what you do in the next 7 to 30 days will determine whether you can hold the right people accountable. The evidence is disappearing while you read this. Surveillance DVRs in these facilities are often set to overwrite in as little as a week. Incident reports are being “finalized” by risk management. We are ready to stop that clock today.

The Architecture of Systemic Negligence in Central Texas

Nolanville sits at the center of one of the fastest-growing family corridors in Texas. Between the youth sports culture tied to Killeen ISD and Belton ISD and the military communities surrounding Fort Cavazos (formerly Fort Hood), the demand for indoor entertainment is massive. This has led to a saturation of trampoline parks and family entertainment centers like Urban Air in Killeen or the Xtreme Jump flagship in Temple.

When thousands of children are airborne simultaneously on a Saturday afternoon along the I-14 corridor, the risk of injury is not an “act of God.” It is a statistical certainty if the operator fails to follow the standards. The industry knows this. That is why they wrote ASTM F2970.

Most parents believe the government inspects these parks. In Texas, they are wrong. Texas is one of 39 states with no comprehensive state trampoline park safety law. The Texas Department of Insurance regulates only the Class B inflatable attractions inside the park—like the Sky Rider ziplines or bungee tramps—but the main trampoline decks, where the most catastrophic injuries happen, are statutorily excluded.

This regulatory vacuum creates a system where the “industry standard” is whatever the park feels like following that day. When an 80-pound child is allowed on the same bed as a 200-pound adult, or when a foam pit is compacted because no one rotated the blocks for three weeks, the park is violating the safety floor their own peers established.

We recently filed a $10 million lawsuit involving rhabdomyolysis and acute kidney failure — the same medical physiology we see in children who jump for extended periods at these parks without water or breaks. We have sued BP, Walmart, and Amazon. We have seen how national conglomerates like Sky Zone, Inc. (renamed from CircusTrix LLC and backed by Palladium Equity Partners) and Unleashed Brands (the parent of Urban Air, recently acquired by Seidler Equity Partners) use franchise layers to hide. We know how to find the money, and we know how to prove the breach.

The Signature Mechanisms: How Physics Maims a Child

The defense will call your child’s injury a “freak accident.” Our biomechanical experts will call it by its real name. To win a case in Nolanville, we must explain the physics that the park’s lawyers want to ignore.

The Double-Bounce Multiplyer (The Catapult Effect)

The most frequent catastrophic mechanism in commercial parks is the double-bounce energy transfer. This occurs when a heavier jumper lands on the trampoline bed just as a lighter jumper—usually a child—is beginning their push-off phase.

The physics are brutal. The trampoline bed stores the kinetic energy of the 200-pound adult’s landing. When that energy is released into the 60-pound child, it multiplies the child’s launch force by up to 4x. The child is no longer jumping; they are being thrown by a machine. This is exactly why ASTM F2970’s age and weight separation provisions exist. When a park in Temple or Killeen ignores these rules during a busy birthday party, they are turning a play space into a catapult.

The injuries we see from this mechanism include:

  • Comminuted femoral shaft fractures: A clean break of the thigh bone, requiring surgery and often the placement of intramedullary nails.
  • Salter-Harris growth plate fractures: If a fracture line extends through the growth plate (the physis) of a nine-year-old’s leg, that bone may not grow straight or grow at all for the next decade.
  • Cervical spine hyperflexion: The child is launched off-axis and lands on their head or neck, leading to SCIWORA (Spinal Cord Injury Without Radiographic Abnormality).

The Foam Pit Illusion

Foam pits in parks like Altitude or Get Air look soft, but they are often the most dangerous attraction in the building. A “pit” is supposed to provide uniform deceleration. However, polyurethane cubes compact over time. If a park skips its weekly rotation schedule, the cubes lose their bounce.

Imagine a teenager doing a backflip into a pit that is only two-and-a-half feet deep because the foam has been compressed. They land head-first and hit the hard unpadded subfloor. We call this axial loading. It is the same mechanism that killed Ty Thomasson at SkyPark Phoenix in 2012, a case that led to Arizona’s “Ty’s Law.”

Beyond the impact risk, foam pits are literal bacterial reservoirs. They absorb sweat, saliva, and vomit from thousands of children. We are currently tracking cases of MRSA and group A strep acquired after foam pit collisions. Because the interior of a foam block cannot be sanitized, a park that doesn’t replace its foam every year is operating an infectious disease hazard.

The Adjacent Attraction Pivot: Sky Riders and Go-Karts

The “trampoline park” in Nolanville is likely now a “Family Entertainment Center” (FEC). Chains are bolting on attractions like go-karts and Sky Rider indoor coasters under the same waiver.

In late 2025, a six-year-old girl named Emma Riddle was killed at an Urban Air in Florida when an electric go-kart reportedly surged forward on its own, crashing into a wall. In Sugar Land, Texas, a fourteen-year-old girl fell thirty feet from a climbing wall because an attendant strapped the harness but neglected to attach the fall-protection line.

Waivers are often drafted specifically for trampolines. They may not even cover the go-kart or the climbing wall failure that hurt your child. At Attorney911, we analyze the scope of the agreement. If the park’s lawyers used a 2010 trampoline template for a 2026 go-kart track, that waiver may be a legal nullity.

The Bell County Case Build: How We Prove Negligence

When you retain us, our paralegal team and investigators deploy a multi-stage forensic protocol within 48 hours. We don’t ask the park for permission; we demand accountability.

  1. The 24-Hour Spoliation Letter: We send a formal litigation-hold demand by certified mail to the local Nolanville-area operator, the franchisor HQ, and the insurance carrier. This stops the automatic deletion of surveillance video. We don’t just want “the clip” of the accident; we want the 72 hours of footage preceding it to show the pattern of understaffing.
  2. Digital Forensics: The “kiosk waiver” is data. We subpoena the audit logs. We want to see the IP addresses, the session timestamps, and the version history. If the park claims you signed Version 7, but their server shows Version 7 wasn’t uploaded until after your injury, their defense is dead.
  3. Incident Report Reconstruction: The report the manager gave you is often a sanitized “final” version. We pull the document metadata to see the original handwritten notes from the teenage attendant who was first on the scene. The “revision” is often where they delete the admission of fault.
  4. Expert Retention: Within seven days, we have a biomechanical engineer and an ASTM-compliance expert analyzing the scene. If it’s a pediatric fracture, we retain a pediatric orthopedic surgeon to project the lifelong cost of a growth plate injury.
  5. Chain-Wide Subpoenas: If your child was hurt on a Sky Rider at an Urban Air, we subpoena the incident history for every Sky Rider in the country. Under Federal Rule of Evidence 404(b), we prove a pattern: the same attraction, the same failure, a different child.

Why the Waiver Is Not a Wall

The park’s insurance adjuster will call you within two days. She will be polite. She will ask about your child’s surgery. Then she will casually mention that you “signed a waiver” so the park isn’t responsible.

In Texas, that is often a lie.

While Texas is generally a contract-friendly state, the “fair notice” doctrine established in Dresser Industries v. Page Petroleum requires a waiver to be conspicuous and explicitly use the word “negligence.” Many kiosk waivers fail this test.

More importantly, the Texas Fourteenth Court of Appeals in Munoz v. II Jaz Inc. established a clear rule: a parent cannot sign away a minor child’s personal injury claim in Texas. Your signature may bar your claim for medical bills, but it does not bar your child’s claim for their pain, their suffering, and their future earning capacity.

Finally, no waiver in the United States protects against gross negligence. When a Harris County jury returned an $11.485 million verdict in the Cosmic Jump case, it was because the park knew about the tear in the equipment and chose to keep the attraction open. That is conscious indifference. It is gross negligence. It is also why we win.

The Hidden Costs of a Pediatric Injury

Parents often undervalue their own cases because they are only looking at the ER bill. But a catastrophic injury to an eight-year-old child in Nolanville has a 70-year horizon.

We work with Certified Life Care Planners (CLCPs) to calculate:

  • The Growth Arrest Cascade: If a growth plate is destroyed at age seven, the leg will grow crooked or shorter over the next decade. This requires annual specialist visits, potential corrective osteotomies at age 14, and lifetime gait adjustments.
  • The TBI Cognitive Toll: A “concussion” at age six isn’t just a headache. It can lead to academic regression, special education needs, and permanent executive function damage that won’t show its full impact until they try to get a job at age 22.
  • The Post-Splenectomy Risk: If a child’s spleen was ruptured and removed, they face a lifetime risk of OPSI (Overwhelming Post-Splenectomy Infection). They need a lifetime of specific vaccinations and emergency antibiotic protocols.

We don’t settle for the medical bills. We settle for the child’s entire future.

Frequently Asked Questions for Nolanville Families

Can I sue if I signed the waiver?

Yes. As discussed, Texas has specific “fair notice” and conspicuousness requirements that many park waivers fail. Furthermore, Texas law generally prevents parents from waiving the tort rights of a minor child. If the park was grossly negligent—meaning they knew of a danger and ignored it—the waiver is irrelevant.

Should I let my kid go to a birthday party at a jump park?

Birthday parties are the highest-risk events. The floor is at capacity, attendants are stretched thin, and children are often crashing from sugar and overexcitement. If your child attends, we recommend designating a “rail parent” whose only job is to stand at the observation deck and watch the child continuously—not sit in the party room eating pizza.

What if the park didn’t call 911?

In multiple Tripadvisor reviews for Urban Air Southlake, parents alleged that “employees are specifically instructed by management to NOT call 911.” If the park delayed medical care for your child, that is evidence of gross negligence and an industry-wide tactic designed to minimize the official record of the accident. We will subpoena the park’s “emergency response plan” to prove they violated their own supposed duties.

How much does a trampoline park lawyer cost?

At Attorney911, we work on a contingency fee basis. This means we take 33.33% if the case settles before trial, or 40% if we try the case. We advance every cost ourselves—the thousands of dollars for the biomechanical engineer, the life care planner, and the medical experts. You pay nothing unless we recover money for your child.

Is my homeowner’s insurance going to cover this?

If the injury happened on a backyard trampoline, the answer is usually no. Most primary homeowners’ policies (HO-3/HO-5) in Bell County specifically exclude trampoline injuries unless you have a separate endorsement. However, we often find coverage through the manufacturer’s product liability policy or the retailer-as-seller, such as Walmart or Amazon.

Does it matter which brand — is Sky Zone safer than Urban Air?

The brand matters less than the staff. All major chains—Sky Zone, Urban Air, Altitude, DEFY—use the FEC model now. All of them use minimum-wage monitors (typically 16-19 years old) with an average of 2-4 hours of training. If the park isn’t enforcing the “one jumper per bed” rule or isn’t checking harnesses on the climbing wall, the brand on the sign is just a marketing sticker for a dangerous environment.

What if I didn’t actually sign — my in-laws or the friend’s parent did?

Texas Family Code § 153.073 is very specific. Only a legal parent or court-appointed conservator has the authority to bind a minor child. If a grandmother, an aunt, a teacher, or a friend’s parent clicked the iPad at check-in, they had no legal authority to bind your child. The waiver is void from the start.

Why Nolanville Parents Choose Attorney911

We represent families. We represent children. We represent the parent who spent last night in a plastic hospital chair because a corporation decided that a $12-an-hour monitor was enough to keep their child safe.

Ralph Manginello brings federal court experience and a 25-plus year track record of making large corporations pay. Lupe Peña brings the insider knowledge of how insurers try to cheat you. We are currently litigating a $10 million acute kidney failure case, utilizing the same medical experts required for trampoline rhabdomyolysis and compartment syndrome.

You didn’t ask for this fight. You went to a park to celebrate a friend or let out some energy on a hot Texas afternoon. You signed the document because the line was long. You are not to blame. The corporate conglomerate that collected your money and failed its duty under ASTM F2970 is the one responsible.

The clock is running. The video at that park is being overwritten right now. The manager is potentially editing the incident report metadata this afternoon. Do not give them a head start.
