Explosive experts: The Las Vegas blast could have been worse
- Experts told BI the explosives detonated in an apparent attack outside a Trump hotel didn't appear sophisticated.
- One explosives expert said the incident, where the driver was an active-duty Army service member, appeared "poorly executed."
- Authorities said the explosives were "not what we would expect from an individual with this type of military experience."
Explosive experts told Business Insider the damage from the materials detonated inside a Tesla Cybertruck in front of the Trump International Hotel in Las Vegas would likely have been worse if the items used had been more sophisticated.
The explosive-laden Cybertruck, which authorities say carried gasoline tanks, camping fuel, and large firework mortars, injured at least seven people. The driver, an active-duty Army service member named Matthew Alan Livelsberger, shot himself moments before the explosives detonated on Wednesday, authorities said.
Tesla CEO Elon Musk took to social media in the wake of the incident to praise the Cybertruck's design and suggest it helped limit the damage of the explosion.
Nick Glumac, a mechanical science and engineering professor at the University of Illinois Urbana-Champaign, told BI that the volume of the explosion was likely due to the types of explosives used. Glumac said this was a "poorly executed" incident if the intent was to cause major damage.
"It would be very difficult to get the types of fuels here to make into a large scale destruction kind of event," Glumac said.
Glumac said similar improvised explosive device blasts look very different from what occurred on January 1. He also pointed to the Oklahoma City Bombing in 1995, when Army veteran Timothy McVeigh detonated an explosive-laden rental truck that killed 168 people and reduced a third of the federal building to rubble.
"That was very carefully planned. They knew what they were doing," Glumac said about the Oklahoma City Bombing, adding that the Cybertruck explosion on January 1, by contrast, appeared "very improvised."
'The level of sophistication is not what we would expect from an individual with this type of military experience'
Car and truck bombs were a key feature of the wars in Iraq and Afghanistan, to which the suspect deployed at least three times. In many of those instances, vehicles were packed with enough explosives to blast fortified positions or take down buildings. The war in Ukraine has similarly suggested that heavily armored vehicles and tanks can be used as rolling car bombs.
Officials spoke about the explosive materials used in the incident during a Thursday press conference.
"The level of sophistication is not what we would expect from an individual with this type of military experience," Kenny Cooper, an assistant special agent in charge for the Bureau of Alcohol, Tobacco, Firearms and Explosives, said at a Las Vegas Metropolitan Police press conference, adding that most of the materials in the vehicle were to "help fuel a greater explosion."
Ali Rangwala, a fire protection engineering professor at Worcester Polytechnic Institute, said that the driver may have miscalculated the explosion, and it might not have been released instantaneously.
"Some of the explosives might not have triggered on time systematically," Rangwala said.
"The only way to create an instantaneous energy release, as in the case of a bomb, is for all of the energetic material to ignite in micro- or milli-seconds," Jim Wesevich, a global service line leader of forensics at safety and security firm Jensen Hughes, told BI in written commentary.
A military official told BI that Livelsberger "wasn't a bomb maker." But his military occupational specialty (MOS) within the 10th Special Forces Group was 18Z, making him a special forces operations sergeant, which the Army says, "trains and maintains proficiency in all major duties associated with Special Forces."
Cooper said it was too early to know if there was "sophisticated connectivity" to the components or to "give any determination" as to how the explosion was initiated. Officials said they discovered consumer fireworks, mortars, aerial shells, fuel enhancers, and explosive targets that Cooper said could be purchased at "any sporting goods store."
Experts say a vehicle's design may shape the trajectory of a blast
Elon Musk, in a social media post Wednesday, called the Cybertruck the "worst possible choice for a car bomb, as its stainless steel armor will contain the blast better than any other commercial vehicle."
Kevin McMahill, sheriff of the Las Vegas Metropolitan Police Department, said the Cybertruck's design helped limit the explosion.
"The fact that this was a Cybertruck really limited the damage that occurred inside of the valet because it had most of the blast go up and through the truck and out," McMahill said in a briefing.
Rangwala said the damage may have been partly limited because a Cybertruck's roof, which includes a large glass pane, would clear pressure from inside the vehicle early in the explosion. The pressure from an explosion would be felt on all sides equally if it wasn't relieved by going upward through the roof, he said.
Glumac and Brian Meacham, an engineer and director of risk and regulatory consulting at Crux Consulting LLC who spoke to BI over email, said that they would have expected similar scenarios if the incident took place in a traditional pickup truck.
Michael Villahermosa, a US Army commander with a background in explosive ordnance disposal, said on X that photos of the items used in the blast suggest the explosives were "poorly constructed and poorly thought out."
As he said on X, "People are using the Las Vegas bombing to show the quality of the Cybertruck," when, in his view, "it shows the quality of the explosive device that was used."

Scoop: Biden notifies Congress of $8 billion arms sale to Israel
The State Department has notified Congress "informally" of an $8 billion proposed arms deal with Israel that will include munitions for fighter jets and attack helicopters as well as artillery shells, two sources with direct knowledge tell Axios.
Why it matters: This will likely be the last weapons sale to Israel the Biden administration approves.
- It comes amid claims from Israeli Prime Minister Benjamin Netanyahu and his supporters in recent months that Biden had imposed a silent "arms embargo" on Israel.
- Some Democrats pushed the administration to condition arms sales to Israel based on Israel's handling of the war effort and the humanitarian situation in Gaza, but Biden declined to do so.
- This is a long-term agreement, according to the sources. Some production and delivery of the munitions can be fulfilled through current U.S. stocks, but the majority will take one or more years to deliver.
Zoom in: The sources said the arms sale β which needs approval from the House and Senate foreign relations committees β includes AIM-120C-8 AMRAAM air-to-air missiles for fighter jets to defend against airborne threats, including drones.
- The sale also includes 155mm artillery shells and Hellfire AGM-114 missiles for attack helicopters.
- The proposed deal also includes small diameter bombs, JDAM tail kits that turn "dumb bombs" to precision munitions, 500-lb warheads and bomb fuzes.
What they're saying: One source familiar with the arms sale said the State Department told Congress the deal is aimed at "supporting Israel's long-term security by resupplying stocks of critical munitions and air defense capabilities."
- "The President has made clear Israel has a right to defend its citizens, consistent with international law and international humanitarian law, and to deter aggression from Iran and its proxy organizations. We will continue to provide the capabilities necessary for Israel's defense," a U.S. official said.
Before and after photos show how a fire destroyed a market where much of the world's secondhand clothes end up
- A fire devasted one of the world's largest secondhand clothing markets in Accra, Ghana.
- Kantamanto Market receives 15 million garments weekly and employs some 30,000 people.
- An advocacy group urged the global fashion industry to provide relief.
A fire devastated one of the world's largest secondhand clothes markets in Accra, Ghana.
The blaze started Thursday and destroyed as much as two-thirds of Kantamanto Market, which employs about 30,000 clothing traders and receives some 15 million garments weekly from wealthy countries like the US, the UK, and China.
Thousands of people lost their stalls. Ghana National Fire Service said the fire was fully extinguished, and no injuries or fatalities were reported. They are still investigating the cause of the fire.
Now, clean-up efforts are underway, and advocacy groups are calling on the global fashion industry to help provide relief.
"This is a critical moment for the global fashion ecosystem to show solidarity, not just by recognizing the value of secondhand markets, but by providing tangible help to rebuild and sustain them," Daniel Mawuli Quist, creative director of The Or Foundation, said in a statement.
The fire calls attention to the global fashion industry's lack of alternatives for waste handling.
Workers in Kantamanto Market resell and remanufacture millions of garments. But the rise of fast fashion has overwhelmed Accra with textile waste piling up in gutters, landfills, and beaches. An estimated 40% of garments go unsold, The Or Foundation found. The nonprofit in Ghana conducts research and offers grants and job training to workers in Kantamanto Market.
The Or Foundation pledged $1 million to relief efforts and set up a fund to raise money for rebuilding the market and providing financial assistance to vendors.
