Boom Supersonic Achieves Supersonic Flight

The first civil supersonic jet made in America breaks the sound barrier in historic Mojave airspace

XB-1 demonstrator provides the foundation for Boom's supersonic airliner, Overture

MOJAVE, Calif. and DENVER, Jan. 29, 2025 /PRNewswire/ -- Boom Supersonic, the company building the world's fastest airliner, Overture, today announced the successful first supersonic flight of its XB-1 demonstrator aircraft at the Mojave Air & Space Port in California. Boom designed, built, and flew the world's first independently developed supersonic jet—the first civil supersonic jet made in America.

Flown by Boom Chief Test Pilot Tristan "Geppetto" Brandenburg, XB-1 entered the supersonic corridor and reached an altitude of 35,290 feet before accelerating to Mach 1.122 (652 KTAS or 750 mph) – breaking the sound barrier for the first time. Historically, supersonic aircraft have been the work of nation states, developed by militaries and governments. XB-1's supersonic flight marks the first time an independently developed jet has broken the sound barrier.

"XB-1's supersonic flight demonstrates that the technology for passenger supersonic flight has arrived," said Boom Supersonic founder and CEO Blake Scholl. "A small band of talented and dedicated engineers has accomplished what previously took governments and billions of dollars. Next, we are scaling up the technology on XB-1 for the Overture supersonic airliner. Our ultimate goal is to bring the benefits of supersonic flight to everyone."

The first supersonic jet built from airliner technology, XB-1 incorporates many of the key features found on Overture, such as carbon fiber composites, digital stability augmentation, and an augmented reality vision system for landing visibility.

Following its inaugural flight in March 2024, XB-1 completed a rigorous series of 11 human-piloted test flights under increasingly challenging conditions to evaluate systems and aerodynamics. Over the course of the flight test campaign, the XB-1 team systematically expanded the flight envelope through subsonic, transonic, and supersonic speeds—while taking smart risks and maintaining safety as top priority.

"It has been a privilege and a highlight of my career to be a part of the team that achieved this milestone—every single member of this team was critical to our success," said Tristan "Geppetto" Brandenburg, Chief Test Pilot for Boom Supersonic. "Our discipline and methodical approach to this flight test program created the safety culture that made a safe and successful first supersonic flight possible. With the lessons learned from XB-1, we can continue to build the future of supersonic travel."

XB-1 provides the foundation for Overture, validating key technologies while establishing a safety-first culture. Technologies proven through XB-1's test program that will also apply to Overture include:

• Augmented reality vision system: XB-1 and Overture both have a long nose and a high angle of attack for takeoff and landing, which makes it difficult for pilots to see the runway in front of them. Both aircraft leverage an augmented reality vision system to enable excellent runway visibility—without the weight and complexity of a moveable nose like Concorde's.
• Digitally-optimized aerodynamics: Engineers used computational fluid dynamics (CFD) simulations to explore thousands of designs for XB-1. The result is an optimized design that combines safe and stable operation at takeoff and landing with efficiency at supersonic speeds. CFD is also used extensively in the Overture program.
• Carbon fiber composites: Both XB-1 and Overture are almost entirely made from carbon fiber composite materials, resulting in a sophisticated aerodynamic design with a strong, lightweight structure.
• Supersonic intakes: XB-1's engine intakes slow supersonic air to subsonic speeds, efficiently converting kinetic energy into pressure energy, allowing conventional jet engines to power XB-1 from takeoff through supersonic flight. Learnings from the development of XB-1's specialized intakes are being applied to Overture and its purpose-built turbofan engine, Symphony.

XB-1's supersonic flight took place in the same historic airspace where Chuck Yeager broke the sound barrier for the first time in 1947, among many other historic firsts. The first supersonic flight of XB-1 marks the first human-piloted civil supersonic flight since Concorde's retirement over 20 years ago, paving the way for the return of commercial supersonic flight onboard Overture. Overture will carry 64-80 passengers at Mach 1.7, about twice the speed of today's subsonic airliners, on over 600 global routes.

Overture has an order book of 130 orders and pre-orders from American Airlines, United Airlines, and Japan Airlines. In 2024, Boom completed construction on the Overture Superfactory in Greensboro, North Carolina, which will scale to produce 66 Overture aircraft per year. Optimized for speed, safety, and sustainability, Overture and its bespoke propulsion system, Symphony, are designed to run on up to 100% sustainable aviation fuel (SAF).

Boom Supersonic Achieves Supersonic Flight

• New framework brings together Aon's Risk Capital and Human Capital data with public sentiment analysis from Gallup to create a portfolio view of risk
• Creates further clarity into how risks compound across four megatrends, how resilience is built and activated and where targeted actions can most effectively influence performance

DUBLIN, Jan. 16, 2026 /PRNewswire/ -- Aon plc (NYSE: AON), a leading global professional services firm, announced today that it is releasing insights from a new, data-driven tool to help organizations build sustainable resilience and unlock growth: Aon's Resilience Quotient.

Developed in collaboration with Gallup, Aon's Resilience Quotient responds to a critical insight: in a time of increasing populism and fragmented sources of information, quantitative data alone is not enough to make long-term decisions. Combining public sentiment on global issues with risk and people data and analytics enables greater clarity and confidence to invest and grow amidst uncertainty and volatility.

By integrating Aon's proprietary Risk Capital and Human Capital analytics with the results of Gallup's World Poll covering 140 countries for more than 20 years, the firm's Resilience Quotient captures both objective conditions and subjective sentiment, revealing where sentiment signals hidden risks and potential opportunities to achieve greater resilience. This system-level view enables leaders to spot emerging risks sooner, prioritize resilience investments and move from reactive risk management to proactive decision-making.

"When making decisions around investment, workforce or managing geopolitical risk, a portfolio view is far superior to a siloed perspective," said Greg Case, president and CEO of Aon. "Understanding sentiment can be an opportunity signal or an early warning. Leaders who are limited to only some of the relevant metrics risk missing the signals that matter most. Aon's Resilience Quotient delivers an integrated view to help organizations act decisively, strengthen resilience and unlock sustainable growth."

Four interconnected megatrends – Trade, Technology, Weather and Workforce – are reshaping the global operating environment in ways that traditional models struggle to anticipate. Aon's Resilience Quotient provides a clearer view of the tradeoffs within these interactions: how trade volatility can amplify technology risk, how climate pressures influence workforce mobility and how sentiment can either reinforce resilience or heighten operational risk, even when the fundamentals appear strong.   

To illustrate the insights from its Resilience Quotient, the firm published three case studies addressing some of the most relevant and urgent issues facing the 2026 global economy:

• Realizing the Opportunity of AI: Securing Data Center Growth
  Data centers are the backbone of the digital economy and with nearly $1.3 trillion projected to be invested globally in data centers by 2030, their rapid expansion brings unprecedented risks. Aon's Resilience Quotient shows that resilience varies sharply at the sub-national level, often more than underlying risk. Within the U.S., Iowa emerges as the most resilient destination for data center development, combining very low overall risk with exceptionally strong trade and weather resilience.

  "Aon's Resilience Quotient shows that Iowa's resilience–risk balance is roughly twice the national median, demonstrating how governance quality, institutional confidence and preparedness materially shape long-term infrastructure outcomes," said Joe Peiser, CEO of Commercial Risk Solutions at Aon. "This underscores the opportunity for leaders who understand the combined effect of low risk, resilient trade and weather systems and a strong foundation of public trust — factors that ultimately determine where AI infrastructure can grow at scale."

"This underscores the opportunity for leaders who understand the combined effect of low risk, resilient trade and weather systems and a strong foundation of public trust — factors that ultimately determine where AI infrastructure can grow at scale."

• Workforce Transformation: AI Adoption and the Next Generation Workforce 
  The acceleration of AI adoption is transforming the workforce, but most organizations face a critical gap between the demand for AI skills and their readiness to adapt. The Resilience Quotient highlights how workforce engagement, trust and institutional preparedness are essential to harnessing AI's potential, making resilience the key differentiator between organizations that thrive through change and those that risk falling behind.

  "Aon's Resilience Quotient equips leaders to navigate rapid AI change with confidence," said Lisa Stevens, chief administrative officer at Aon. "These insights help create the conditions for early‑career employees to build the skills and confidence they need — so instead of losing a generation of talent, we cultivate one that is more capable and resilient than ever."

"These insights help create the conditions for early‑career employees to build the skills and confidence they need — so instead of losing a generation of talent, we cultivate one that is more capable and resilient than ever."

• Rethinking Humanitarian Finance: A New Approach to Forced Migration
  Over 120 million people are currently displaced by conflict, climate and systemic crises, reshaping societies and economies worldwide. Aon's Resilience Quotient highlights Venezuela and Colombia to illustrate the tradeoffs between investing resources at the source of migration — supporting those facing institutional erosion, food insecurity and economic collapse — or directing investment to more stable countries like Colombia that are absorbing people fleeing unlivable conditions.

  "Forced displacement results from extreme weather and man-made disasters like conflict and economic failure," said Bridget Gainer, chief public affairs officer at Aon. "If we could leverage the forecasting and financial capability of insurance to better predict and more quickly mitigate the impact of this volatility, we could help create conditions that allow populations to remain and rebuild in their home countries."

"Resilience is not a single blueprint, it's the way systems mitigate, adapt and transform under pressure. Aon's Resilience Quotient functions as a pressure gauge, surfacing the trade‑offs and early signals that help leaders strengthen resilience where it matters most," said Joe Daly, managing partner at Gallup. "We're proud to collaborate with Aon to combine Gallup's global sentiment analytics with Aon's Risk Capital and Human Capital data, turning confidence into actionable insight."

New insights from Aon's Resilience Quotient suggest that going forward, resilience priorities will shift from static risk management to dynamic, localized strategies. As disruptions become more complex and frequent, organizations will need to tailor resilience investments to specific geographies, sectors and even sub-regional contexts. Aon's Resilience Quotient is supported with a real-time analytics and AI-enabled insights platform, built by Quantum Rise, providing deeper visibility into evolving risk and resilience signals as conditions change.

Aon and Gallup will join global decision-makers at the World Economic Forum Annual Meeting to advance these critical discussions on restoring confidence and unlocking sustainable growth.
