SION, Switzerland, May 6, 2025 -- H55, the pioneering electric aviation company and the technological spin-off of the Solar Impulse project, has successfully completed the first leg of its 8-state U.S. tour—making a powerful debut in Florida and demonstrating the promise of clean, quiet, and efficient flight. As part of its visionary Across USA Tour, H55 engaged flight schools, instructors, and industry leaders—showcasing the transformative potential of its certified electric propulsion system and accelerating market interest in the Bristell B23 Energic.
With its all-electric Bristell B23 Energic aircraft, H55 completed 36 demonstration flights and hosted 12 open house events across 14 Florida airports. The company showcased its zero-emission electric propulsion technology to a wide range of audiences —including flight schools, aeronautical universities, aerospace professionals, professional pilots, aviation communities, airport authorities, and industry enthusiasts.
Industry Momentum
From a strong showing at the Sun 'n Fun Aerospace Expo to final stops in Central Florida, the H55 Across USA Tour engaged:
- 14 Airport-to-airport flights
- 36 Demonstration flights
- 12 Static events
- 30 Certified Flight Instructors (CFI/CFII)
- Aeronautical and aviation Professors Embry-Riddle Aeronautical University, Liberty University, and Florida Institute of Technology
- 2 Aerospace experts
- 18 Flight schools
- 10 Fixed-Base Operators (FBOs)
The Energic aircraft's aerodynamic design offers smooth, responsive handling and a remarkably quiet cockpit. Powered by H55's intelligent battery systems, the aircraft provides compelling proof that electric propulsion is poised to transform general aviation, regional transport aircraft operations, and pilot training.
"This Florida tour marks a turning point—flight schools, instructors, and the broader aviation community are embracing the shift to electric. The future of flight is quiet, efficient, and electric. Our time in Florida demonstrated the real-world readiness of H55's certified electric propulsion system and intelligent energy management, along with strong interest from flight educators in adopting cleaner, quieter, and more cost-effective training solutions," said Kristen Jurn, H55 US Sales Manager.
Voices from the Field: Flight Training and Innovation Experts React
"The Bristell flies light on the stick—but the biggest difference is how quiet and smooth it is. The controls are responsive, even during taxi, and you can take your headset off mid-flight and carry on a conversation. From both a training and maintenance perspective, being able to bring the power to zero without riding the brakes is a big deal—brake replacements are among the most frequent maintenance issues."
— Adam Valencic, Multi-Engine Instructor & President, First Landings Aviation
"The overall handling was very nice, and the aircraft felt robust—even with baggage onboard and full communication with ATC. It's quiet, responsive, and a great fit for instructional programs. As technology advances, I see electric aircraft playing an increasingly important role in flight training."
— Tiago Dikerts de Tella, Assistant Chief Flight Instructor, Embry-Riddle Aeronautical University
"The Bristell combined with H55's electric propulsion is a brilliant pairing. The quiet, smooth flight experience—from taxi to takeoff—was a real pleasure. This is the beginning of a new era that will revolutionize general aviation—and perhaps even commercial flight."
— Scott Vangen, NASA (Ret.), Alternate Payload Specialist Astronaut, STS-67
A Proven Concept, Ready to Scale
Gregory Blatt, Co-Founder and Across America Mission Director, said: "With Solar Impulse, we proved that clean aviation was possible — flying around the world without a single drop of fuel.
Now with H55, we're taking that vision further, delivering certified electric propulsion systems that are scalable, and ready for real-world use. Electric flight is no longer a future concept— it's here, meeting the highest safety standards while reducing maintenance, lowering costs,
and enabling cleaner, quieter, and more reliable operations. For flight schools, general aviation, and the future of air mobility, this is a turning point."
Looking Ahead
H55's certified electric propulsion and intelligent battery systems take center stage as the company continues its 5-month journey across seven more states. With the Florida segment complete, the B23 Energic will lead the next phase of the tour, inviting representatives from flight schools, fixed-base
operators (FBOs), military bases, college aviation programs, local educators, aviation enthusiasts, and industry leaders to experience firsthand how electric aviation is transforming general aviation and flight training.
Next up: Alabama and Arizona in May.
Both states play key roles in aviation and aerospace, offering fertile ground for introducing sustainable flight technologies to training hubs and research institutions. H55's propulsion systems are ideally suited to meet the growing demand for quiet, efficient, and emissions-free solutions in these dynamic general aviation ecosystems.
