The X-66A is the X-plane specifically aimed at helping the United States achieve the goal of net-zero greenhouse gas emissions by 2050.
Boeing will work with NASA to modify an MD-90 aircraft, and build the X-66A, by shortening the fuselage and replacing its wings and engines.
The resulting demonstrator aircraft will have long, thin wings with engines mounted underneath and a set of aerodynamic trusses for support. The design, which Boeing submitted for NASA’s Sustainable Flight Demonstrator project, is known as a Transonic Truss-Braced Wing.

The new X-plane seeks to inform a potential new generation of more sustainable single-aisle aircraft – the workhorse of passenger airlines around the world.
NASA Administrator Bill Nelson, said:
“At NASA, our eyes are not just focused on stars but also fixated on the sky. The Sustainable Flight Demonstrator builds on NASA’s world-leading efforts in aeronautics as well as climate. The X-66A will help shape the future of aviation, a new era where aircraft are greener, cleaner, and quieter, and create new possibilities for the flying public and American industry alike.”

This article contains wonderful writing. Because of the manner you structured your ideas, your findings are quite understandable.
The X-66A is NASA’s latest experimental aircraft, designed to usher in a generation of more sustainable commercial aircraft with the goal of drastically reducing emissions and fuel consumption. It is the first X-plane directly focused on achieving net-zero emissions for the U.S. aviation industry by 2050.
The X-66A is part of the Sustainable Flight Demonstrator project, a collaboration between NASA and Boeing.
The goal: to develop technology for the next generation of fuel-efficient single-aisle aircraft, which account for nearly half of global aviation emissions.
The idea of such a radical redesign to achieve net-zero emissions is incredibly ambitious. It reminds me of learning something new – sometimes you feel like you’re swinging for the fences, like in Doodle Baseball! You don’t always connect perfectly, and there are definitely setbacks. But each attempt, each tweak to the design, each new piece of information is a lesson learned.
The X-66A represents a groundbreaking leap towards sustainable aviation, promising to redefine the skies with its innovative design and commitment to net-zero emissions by 2050.

That’s fantastic! It’s inspiring to see NASA focusing on sustainable aviation. Makes me think about how much faster technology is moving now compared to when I was a kid. Back then, waiting for dial-up was the norm! Speaking of fast, have you guys ever tested your clicking speed? It’s surprisingly fun. There are some cool CPS test sites online if you’re curious! I wonder if future pilots will need super-fast reflexes to handle these next-gen planes!
An exciting step toward cleaner aviation! The X-66A’s innovative truss-braced wing design could revolutionize single-aisle aircraft, making them greener and quieter—paving the way for a sustainable future.
It’s fascinating to see how they’re modifying an existing MD-90 airframe to test the Transonic Truss-Braced Wing design. Given how much the industry relies on single-aisle jets, this project feels like a much more practical step toward net-zero than just waiting for brand-new engine technology to mature.
The Transonic Truss-Braced Wing design is fascinating, especially considering how much this could change the efficiency of standard single-aisle jets. It’s exciting to see Boeing and NASA repurposing the MD-90 frame to test such a radical aerodynamic shift for a net-zero future. I’m really curious to see how these long, thin wings perform once the test flights officially begin.
X‑66A swaps conventional wings for long, thin ones with truss supports — better fuel efficiency, less noise. This could reshape every short‑haul flight.
“It’s exciting to see projects like the X-66A pushing the boundaries of sustainable aviation!
