"Anyone who has maintained a Black Hawk or Chinook will immediately see it. Chaparral is just easier to maintain. Fewer mechanical systems and fewer people required. That means less time on the ground and more time on the mission." - @USArmy Veteran Joe Lovotti

Chaparral has been putting in the work at our flight test facility completing our latest autonomous flight campaign — and now it's time to take to new skies. New places, new airspaces. Stay tuned! #Chaparral #eVTOL #cargodrone

This is Kevin Noertker. He built planes that fly cleaner, not by waiting for the future but by engineering it into the sky today. As co-founder and CEO of @AmpaireInc, Kevin took a century-old industry and pushed it toward sustainability, retrofitting existing aircraft with hybrid-electric propulsion that’s already flying commercial routes in Hawaii. His core insight: Hybrid isn’t the compromise. It’s the bridge. Infrastructure takes decades. Trust takes flights. Instead of chasing sci-fi jets or waiting for perfect batteries, Kevin built a practical path forward by combining combustion and electric power for safety, scaling through proven airframes, and partnering with the FAA to make electrification certifiable and safe. Under his leadership, Ampaire has logged tens of thousands of hybrid-electric flight miles, cutting fuel burn by up to 50% and proving the future of flight isn’t someday. It’s already airborne. His advice to founders: Be bold but stay grounded. Build trust before transformation. And never bet your business on infrastructure that doesn’t exist yet. The future belongs to builders who make sustainability feel seamless, safe, and ready for takeoff. Watch our full conversation with @KevinNoertker. Link in the comments.

Our heads may be in the clouds, but our feet are firmly on the ground. We have hybrid electric aircraft in the air today. Not tomorrow. Not someday soon. Now.
