US Lawmakers Propose Ending 52-Year Supersonic Flight Ban Over Land
Legislation seeks to modernize FAA rules for supersonic aviation using NASA and private-sector tech, addressing global competition and environmental concerns.
Lawmakers Push to Lift 52-Year Ban on Supersonic Flights Over Land
After more than half a century of silence at supersonic speeds over U.S. territory, lawmakers are proposing a dramatic policy shift that could redefine the future of high-speed civilian aviation. The Supersonic Aviation Modernization Act (SAM), introduced in May 2025, aims to repeal the 1973 Federal Aviation Administration (FAA) regulation that prohibits nonmilitary aircraft from exceeding Mach 1 over land. This move comes as a response to significant advancements in aerospace engineering, particularly in “quiet supersonic” technologies designed to mitigate the disruptive sonic booms that led to the original ban.
The proposed legislation is not just about speed, it’s about positioning the United States at the forefront of global aerospace innovation. With countries like China already investing heavily in next-generation supersonic platforms, U.S. lawmakers argue that maintaining the outdated ban could leave American manufacturers at a strategic disadvantage. In this context, the SAM Act represents a calculated attempt to modernize aviation policy while balancing environmental, economic, and public safety concerns.
As the debate unfolds, stakeholders from government agencies, private industry, environmental organizations, and the general public are weighing in on what could be a defining moment for commercial aviation in the 21st century.
Historical Background: Why the Ban Exists
The Origins of the 1973 Supersonic Flight Ban
The FAA’s 1973 ban on civilian supersonic flight over land, codified in 14 CFR §91.817, was a direct response to widespread public concern over sonic booms. These shockwaves, generated when an aircraft exceeds the speed of sound (approximately 767 mph at sea level), were not only loud but also capable of causing structural damage. During NASA’s 1964 sonic boom tests over Oklahoma City, 72% of residents reported being disturbed by the noise, and 4.3% claimed property damage.
While military aircraft continued to fly supersonically under restricted conditions, commercial ventures like the Concorde were limited to subsonic speeds over land. This restriction severely hampered the Concorde’s commercial viability, as it could not fully exploit its speed advantage on many routes. Environmental concerns, including high-altitude emissions and potential ozone layer depletion, further contributed to the public’s skepticism about supersonic travel.
In effect, the ban created a regulatory environment that discouraged innovation in supersonic aviation for decades. Only now, with significant technological advancements, is the conversation shifting back toward reconsidering these restrictions.
Economic and Strategic Implications
Supporters of the SAM Act argue that the ban has placed the U.S. at a competitive disadvantage in the global aerospace market. With the global supersonic aviation market projected to reach $70.54 billion by 2034, the stakes are high. Private companies such as Boom Supersonic have already invested heavily in research and infrastructure, including a $100 million manufacturing facility in North Carolina expected to create 1,700 jobs by 2030.
Internationally, competition is heating up. China’s COMAC C949 and Lingkong Tianxing’s Cuantianhou projects are pushing the boundaries of supersonic and suborbital flight, with ambitions to halve transcontinental travel times. These developments underscore the urgency for the U.S. to modernize its regulatory framework to keep pace with global innovation.
Senator Ted Budd and Representative Troy Nehls, the bill’s sponsors, have emphasized that the U.S. must not fall behind in this new aerospace race. “To maintain our global leadership in aerospace innovation, we must modernize air travel by lifting the outdated ban on civil supersonic flight,” Budd stated.
“The race for supersonic dominance between the U.S. and China is already underway and the stakes couldn’t be higher, ” Senator Ted Budd
Technological Advances: Making Quiet Supersonics a Reality
NASA’s X-59 QueSST: Reducing the Boom
NASA‘s X-59 Quiet SuperSonic Technology (QueSST) aircraft is a cornerstone of the current push to lift the ban. Designed to reduce the traditional sonic boom to a “sonic thump” of around 75 perceived loudness decibels (PLdB)—roughly equivalent to a car door closing—the X-59 leverages advanced aerodynamics and a 99.7-foot elongated fuselage to disperse shockwaves laterally. (space.com)
NASA plans to conduct community overflight tests between 2026 and 2027 to assess public tolerance for these quieter sonic events. The data collected will be submitted to the FAA by 2028 to inform future regulatory decisions. These efforts aim to replace the current speed-based restrictions with noise-based standards that reflect modern capabilities. (nasa.gov)
According to Larry Cliatt, NASA’s acoustics lead for the QueSST project, “We expect the X-59 sonic thump to be as low as about 75 perceived loudness decibels. That is a lot quieter than the Concorde, which was over 100 perceived loudness decibels.” (nasa.gov)
Boom Supersonic’s XB-1 and Overture
Private industry is also making significant strides. Boom Supersonic’s XB-1 demonstrator aircraft achieved Mach 1.3 in January 2025. By flying at altitudes around 60,000 feet and using the Mach cutoff effect, the XB-1 prevents shockwaves from reaching the ground, effectively eliminating the audible boom.
Boom’s next project, the Overture, is designed to travel at Mach 1.7 and aims to enter commercial service by the end of the decade. The aircraft will use similar boom-mitigation strategies and is being developed with sustainability in mind, including the use of sustainable aviation fuels (SAFs).
Blake Scholl, CEO of Boom Supersonic, views the SAM Act as a pivotal opportunity: “This is our Sputnik moment. If we don’t lead, someone else will.”
Environmental and Regulatory Considerations
Climate Impact and Emissions
Despite the progress in noise reduction, environmental concerns remain a significant hurdle. Supersonic aircraft typically operate at higher altitudes, where emissions such as nitrogen oxides (NOx) can have a greater impact on the ozone layer. Additionally, these aircraft tend to emit more CO2 per passenger-mile than subsonic jets.
NASA estimates that the X-59’s engines will emit approximately 20% more CO2 per passenger-mile. The International Council on Clean Transportation (ICCT) has warned that a fleet of 2,000 supersonic aircraft could contribute up to 0.1 gigatons of CO2 annually—about 1% of global aviation emissions.
To address these concerns, the International Civil Aviation Organization (ICAO) introduced new noise and emissions standards in 2025. However, enforcement across jurisdictions remains inconsistent, raising questions about the global viability of supersonic travel.
Public Acceptance and Legal Framework
Even with quieter technology, gaining public acceptance is not guaranteed. NASA’s upcoming community response surveys will play a critical role in determining whether the public is ready to embrace supersonic flight once again. The FAA must also ensure compliance with the Aviation Safety and Noise Abatement Act, which defines 65 decibels as the threshold for significant noise.
From a legal standpoint, the FAA has the authority under 49 U.S.C. §44715 to revise noise regulations, but any changes must be justified through cost-benefit analyses that consider both economic and public welfare impacts. This means that even if the technology is ready, regulatory approval could still face delays.
Balancing innovation with environmental and social responsibility will be crucial as the FAA considers how to implement the SAM Act, should it pass into law.
Conclusion: A New Era of High-Speed Travel?
The proposed repeal of the 1973 supersonic flight ban marks a turning point in U.S. aviation policy. With the convergence of technological readiness, legislative momentum, and growing international competition, the time may be ripe for a new chapter in commercial air travel. However, this transition will require careful navigation of environmental, regulatory, and societal concerns.
Ultimately, the success of supersonic aviation in the 21st century will depend on three pillars: establishing robust noise certification standards, investing in sustainable propulsion technologies, and fostering international regulatory alignment. If these challenges can be met, the dream of quiet, fast, and efficient air travel over land could soon become a reality.

EASA Proposes Take-Off Performance Monitoring Mandate by 2033
EASA Opinion No 07/2026 proposes mandatory take-off performance monitoring systems on new large commercial aircraft by 2033.
The European Union Aviation Safety Agency (EASA) has formally proposed mandating the installation of take-off performance monitoring systems on all newly produced large commercial aeroplanes by 2033.
Published on September 22, 2026, Opinion No 07/2026 recommends amending European Union regulations to mitigate the risk of runway excursions and aircraft upsets caused by incorrect data entry or erroneous take-off positions. The proposal follows an extensive analysis of historical incidents and targets a six-year implementation window after the rules enter into force.
Mitigating runway excursions and performance errors
The push for a Take-off Performance Monitoring System (TOPMS) addresses a persistent vulnerability in commercial aviation: incidents where incorrect data entry leads to degraded take-off performance. Common errors include entering the wrong aircraft weight, calculating incorrect reference speeds, or initiating the take-off roll from the wrong runway intersection.
According to data published by aviation outlet dlapilota.pl, EASA analyzed 118 events related to erroneous take-off parameters or aircraft positioning that occurred between 1998 and 2023. This dataset included 18 accidents, five of which were fatal. The agency estimates that the proposed TOPMS functions could have prevented 90% of these analyzed events.
The system is designed to monitor parameters and position before the take-off roll begins. For certain large transport aircraft, it will also monitor real-time acceleration and performance during the take-off roll itself, alerting crews if the aircraft is not achieving the required performance to safely become airborne.
The objective is to mitigate, using an on-board alerting system, the risk of large aeroplane accidents or incidents caused by the use of erroneous take-off performance parameters and erroneous take-off positions.
EASA noted in its regulatory filings that these specific errors have the potential to result in runway excursions and aeroplane upsets, which can lead to subsequent loss of control and collision with terrain or obstacles.
Implementation timeline and manufacturer impact
The mandate will apply exclusively to newly produced large aeroplanes used in commercial air transport. EASA explicitly stated that it does not propose mandatory retrofitting of previously produced aircraft. This decision limits the financial burden on current airline operators and focuses the regulatory effort on future production lines from manufacturers like Airbus and Boeing.
The compliance timeline requires the systems to be installed on newly produced aircraft six years after the implementing regulation enters into force. With the European Commission projected to adopt the amendments in 2027, the mandate will take effect in 2033.
The proposed regulatory material is intended to improve safety while limiting manufacturers’ efforts as regards the development and implementation of TOPMS functions to the most beneficial cases. A low-to-very-low cost impact is expected. No environmental and social impacts have been identified.
The regulatory path to Opinion No 07/2026
The publication of Opinion No 07/2026 marks the formal recommendation from EASA to the European Commission to amend Regulation (EU) 2015/640. The rulemaking process began on August 30, 2023, when EASA published the Terms of Reference for Rulemaking Task RMT.0741 to address take-off performance parameters and position errors.
Following nearly two years of development, EASA published a Notice of Proposed Amendment (NPA 2025-01) on July 1, 2025, opening the rules for public consultation. The September 22, 2026 publication includes the final Opinion alongside the Comment Response Document (CRD 2025-01), which addresses industry feedback received during the consultation period.
The European Commission is now tasked with reviewing and adopting the proposed amendments, a process expected to conclude in 2027.
AirPro News analysis
The decision by EASA to exclude legacy aircraft from the TOPMS mandate represents a pragmatic approach to aviation safety regulation. Retrofitting complex avionics and performance monitoring systems into older airframes is technically challenging and cost-prohibitive. By focusing entirely on newly produced aircraft, EASA ensures that the next generation of commercial aeroplanes will feature a critical safety net against human data-entry errors, without grounding or financially penalizing current fleets. We view this as a targeted strategy that prioritizes long-term safety architecture over immediate, disruptive mandates, giving original equipment manufacturers ample time to integrate these systems into their production lines by 2033.

Aviation Coalition Lobbies EU Over Biometric Travel Rules
Five aviation organizations formed a coalition to oppose EU Digital Omnibus rules that could restrict biometric passenger processing at airports.
Five major aviation and travel technology organizations formed a coalition on October 1, 2026, to lobby European Union policymakers against potential restrictions on biometric passenger processing in upcoming digital legislation.
The Responsible Biometrics Travel Industry Coalition, announced in a joint press release, warned that the European Commission’s proposed Digital Omnibus package could inadvertently halt the rollout of automated biometric boarding and security gates at European airports. The group argues that a clear, technology-neutral regulatory framework is necessary to manage growing passenger volumes without requiring massive physical terminal expansions.
The push for a technology-neutral Digital Omnibus
The coalition includes the International Air Transport Association (IATA), Airports Council International Europe (ACI EUROPE), Amadeus, IDEMIA Public Security, and SITA. The group is specifically targeting the data and privacy components of the Digital Omnibus, a legislative package introduced to streamline the European Union’s digital rulebook.
The European Commission originally published the Digital Omnibus proposals on November 19, 2025, aiming to amend existing frameworks including the General Data Protection Regulation (GDPR) and the Artificial Intelligence Act. While a provisional trilogue agreement was reached on the artificial intelligence portion of the Omnibus on May 7, 2026, the data protection and privacy components remain under discussion in the European Council.
The coalition expressed concern that strict interpretations of these pending rules could restrict passengers from voluntarily opting into biometric processing. According to the coalition’s October 1 announcement, biometric technologies are essential for managing projected traffic growth. ACI EUROPE forecasts a 3.3% increase in passenger traffic at Europe’s airports in 2026. The industry maintains that automated systems are the only viable method to process these growing volumes without expanding the physical footprint of existing airport terminals.
Industry investment in paperless travel infrastructure
The aviation sector has invested heavily in biometric infrastructure to create paperless travel experiences, replacing manual passport and boarding pass checks with facial recognition and other identity verification systems. The coalition members represent a significant portion of the global travel infrastructure. IATA represents approximately 330 airlines comprising 80% of total air traffic, while ACI EUROPE represents over 500 airports across 55 countries.
The technology providers in the coalition supply the hardware and software underpinning these initiatives. Amadeus and SITA operate as major multinational information technology providers specializing in passenger processing systems for the global air transport industry. IDEMIA Public Security specializes in identity-related security services, including the facial recognition and biometric identification systems currently used at border control and airport checkpoints.
To support their lobbying efforts, the coalition cited IATA’s 2025 Global Passenger Survey, which found that 74% of travelers are willing to share biometric data in exchange for expedited processing. The group emphasized that any biometric implementation must remain voluntary, protecting passenger choice while ensuring data security.
The economic stakes of European travel efficiency are substantial. The coalition noted that travel and tourism contributed an estimated €1.9 trillion to the European Union’s gross domestic product in 2025, representing 10.5% of the regional economy.
AirPro News analysis
We view the formation of this coalition as a preemptive defensive maneuver by the aviation industry against regulatory creep. European airports and airlines have staked their future operational models on biometric throughput. If the Digital Omnibus imposes rigid consent architectures or localized data processing mandates that are incompatible with current biometric gates, the resulting bottleneck would severely degrade terminal capacity. The coalition’s emphasis on voluntary use is a calculated attempt to align industry efficiency goals with the European Union’s strict consumer privacy mandates, ensuring that the technology can still be deployed for the majority of passengers willing to opt in.

FAA Extends Solace Partnership to Modernize SWIM Network
The FAA extends its Solace partnership to upgrade SWIM with cloud APIs, supporting AI traffic tools including the SMART system trial.
The Federal Aviation Administration (FAA) has extended its partnership with enterprise data platform provider Solace to modernize the data architecture of the U.S. National Airspace System, establishing the infrastructure required for new artificial intelligence air traffic management tools.
Announced in a press release on September 22, 2026, the agreement focuses on upgrading the System Wide Information Management (SWIM) network to deliver Enhanced SWIM Cloud Services (ESCS). This modernization effort replaces legacy manual documentation with machine-readable Application Programming Interfaces (APIs), enabling the bidirectional data flow necessary for predictive traffic management systems currently entering operational trials.
Upgrading the SWIM data backbone
Since 2011, the FAA has utilized the Solace Platform to power the SWIM network. SWIM serves as the national aviation data network, distributing real-time flight plans, surveillance data, weather events, and airspace notices to airlines, the Department of Defense (DoD), air navigation service providers, and the flying public.
The transition to ESCS will shift the network to APIs built on the AsyncAPI standard. This upgrade is designed to improve bidirectional data flow and lay the foundational data groundwork for advanced decision support and next-generation data sharing across the aviation sector.
“When data moves in real-time across the world’s busiest airspace, there is no margin for error,” Joshua Carroll, Chief Technology Officer at Solace, stated in the release. “We are proud the FAA trusts Solace to help power that infrastructure, enabling the future of safe and effective air navigation services.”
Integration with predictive AI traffic management
The Solace partnership extension aligns with a broader multi-billion-dollar effort by the FAA to modernize the aging U.S. air traffic control system and transition from reactive to predictive traffic management, according to reporting by Nextgov/FCW.
The ESCS data backbone will directly support new AI-powered air traffic management tools, including the Strategic Management of Airspace, Routes, and Trajectories (SMART) system. On June 22, 2026, the FAA awarded an $875 million, 12-year contract to Boston-based startup Air Space Intelligence to build the SMART AI system.
According to Quartz, SMART ingests 200 disparate data streams, including airline schedules, weather forecasts, and airport capacity, to predict traffic flows and identify potential conflicts up to two hours before they occur. The live, bidirectional event streams provided by Solace’s ESCS are necessary for these advanced analytics and strategic flight-path optimizations.
The FAA began a 90-day trial of the SMART system on September 21, 2026, at three Washington D.C. area airports: Ronald Reagan Washington National Airport (DCA), Dulles International Airport (IAD), and Baltimore/Washington International Thurgood Marshall Airport (BWI).
AirPro News analysis
The extension of the Solace partnership highlights a critical reality of airspace modernization: artificial intelligence tools are only as effective as the data pipelines feeding them. We view the transition to Enhanced SWIM Cloud Services as a necessary prerequisite for the FAA’s shift toward predictive air traffic control. By replacing manual documentation with machine-readable APIs, the agency is addressing the latency and interoperability bottlenecks that have historically constrained system-wide upgrades. As the SMART system enters its trial phase in the busy Washington D.C. airspace, the performance of this underlying data architecture will be tested under real-world operational loads.
