    Tested the airframe to its limits under real load conditions, verifying structural design, build quality, and materials integrity required for safe flight.

  • Heart Propulsion Testing at Oxnard Facility

    Propulsion test

    Validated all-electric propulsion under flight mission conditions, verifying performance from motor to thrust and proving out propulsion architecture.

  • Flight test operations

    Flight test operations

    Established flight test function, putting in place the people, procedures, and analytics required to safely fly and learn from Heart’s prototype aircraft.

  • FAA inspection

    Airworthiness

    Earned FAA Special Airworthiness Certificate, establishing engagement model, compliance approach, and working relationship with the agency.

  • X1 on the runway

    Flight

    Completed X1’s first flight, bringing Heart’s full-stack aircraft-development capability into the air and launching a new era in commercial aviation.

  • Heart customer engagement.

    Customer engagement

    Activated airline customers, using the aircraft to deepen partner engagement, gather operational feedback, and accelerate commercial momentum.

Heart Aerospace CEO Anders Forslund.

Lower-cost air travel starts with a new kind of aircraft.

With X1, we are entering the electric age of commercial aviation. Electrification gives us the opportunity to build airliners with fundamentally lower operating costs — and to reset the economics of flying.

Heart's vision is abundant air travel: more affordable, frequent and cleaner flights to more destinations, operating from airports closer to where people live and work. X1 is the first step toward making that future real.

Anders Forslund— Founder & CEO, Heart Aerospace

X1 is the proof. ES-30 is the product.

ES-30 is the 30-seat hybrid-electric regional aircraft X1 was designed to enable.
