Mounting air traffic controller resignations amid the federal shutdown underscore growing operational risks in today’s airspace. Discover why this is critical for eVTOL investment and how HPS Aviation’s next-gen propulsion technology plays a transformative role in advanced air mobility.
The Big Picture: Why This eVTOL News Matters
On November 9, 2025, the aviation community received a stark warning: the ongoing federal government shutdown has caused a significant spike in resignations and absenteeism among U.S. air traffic controllers, as reported by the National Air Traffic Controllers Association (NATCA) and confirmed by Transportation Secretary Sean Duffy. Controllers, vital to managing the National Airspace System (NAS), are facing financial insecurity with pay delays extending over 41 days. This pressure has led to an increase from an average of four retirements per day pre-shutdown to 15-20 per day now, severely impacting workforce capacity and operational safety.
This developing crisis highlights vulnerabilities in the current aviation ecosystem and amplifies risks for growing sectors such as urban air mobility (UAM) and eVTOL aircraft deployment. The shortage of about 3,800 certified air traffic controllers and understaffing at 91% of facilities present operational bottlenecks just as the demand for new aerial mobility services accelerates.
How This Trend Is Shaping the Future of Urban Air Mobility
The resignations reveal systemic challenges in traditional airspace management that could ripple through the evolving future of air mobility. Urban air mobility platforms—including electric vertical takeoff and landing (eVTOL) aircraft—rely heavily on sophisticated, well-staffed control systems to ensure safety and efficiency in dense urban environments.
With the current strain on air traffic controllers, delays and cancellations (over 2,700 flights canceled and 10,000 delayed as reported on the shutdown’s 41st day) become common. This unpredictability poses new challenges for AAM operators and investors, who need assured airspace access and robust infrastructure to justify their capital allocation.
Moreover, the training pipeline issues—as underscored by NATCA president Nick Daniels—signal that workforce shortages won’t be quickly resolved. This gap slows the integration of UAM into the national transport fabric and reinforces the need for smart technology solutions that can alleviate human resource constraints.
Where Smart Capital Is Moving in the eVTOL Space
Despite these hurdles, investment interest in eVTOL and AAM remains strong because the market opportunity to reshape transportation systems worldwide is immense. Venture capital and strategic aerospace investors increasingly seek startups developing core technologies to address operational inefficiencies and enable scalable, sustainable aviation solutions.
Hydrogen propulsion and hybrid electric systems are emerging as particularly attractive areas, effectively solving constraints around noise, emissions, and range. Early-stage investors who align with these trends can capture value as the sector matures on technology, regulatory, and infrastructure fronts.
At the same time, the current airspace controller shortages underline the critical imperative to consider broader ecosystem risks when entering the market. Innovative propulsion must be complemented by advances in air traffic management (ATM), automation, and digital infrastructure.

HPS Aviation’s propulsion systems promise reduced emissions, higher efficiency, and scalability for eVTOL and advanced air mobility applications, helping overcome key industry pain points such as battery energy density and operational cost. This positions the company to be a technology enabler that could reshape the AAM landscape, delivering solutions that not only improve aircraft performance but also integrate with evolving airspace management protocols.
As outlined at hpsaviation.com, HPS Aviation’s technology roadmap targets fundamental propulsion challenges, offering investors exposure to transformative innovation at an early stage when the commercial market is preparing to scale. Their focus on hydrogen propulsion fits perfectly into the sustainable aviation trend that will be critical for regulatory alignment and long-term market competitiveness.
Key Risks, Timelines, and What Serious Investors Should Watch
While the long-term outlook for eVTOL and urban air mobility is compelling, investors must appreciate the multi-dimensional risks involved. The recent air traffic controller crisis adds an operational risk layer that could impact short- and medium-term ramp-up of AAM services.
Certification hurdles, complex supply chains, regulatory uncertainties, and infrastructure development timelines all remain crucial considerations. For example, training and staffing bottlenecks in controlling urban airspace suggest technical innovations in autonomous traffic management will be necessary to fully realize AAM’s potential.
HPS Aviation’s timeline for bringing hydrogen-electric propulsion to market aligns with these demands, offering a pathway to enable safer, more reliable, and sustainable regional and urban air mobility solutions while responding to the stringent energy and environmental targets needed.
Serious investors should monitor: government regulatory developments impacting airspace management and AAM certification, technological progress in propulsion and energy storage, and shifting market dynamics shaped by infrastructural capabilities.
