Diachun is noted for his engineering and leadership roles in the development of experimental aircraft, including SpaceShipOne, SpaceShipTwo, and the Scaled Composites Stratolaunch.[2]
Early life and education
Diachun was born in Lexington, Kentucky. He began flying as a teenager, soloing an airplane at age 16 and obtaining his private pilot license shortly thereafter.[2] He attended Purdue University, graduating with a Bachelor of Science in Mechanical Engineering in 1999. He subsequently earned a Master of Science in Aeronautics and Astronautics from Stanford University in 2003.[3]

Diachun joined Scaled Composites, an aerospace company founded by Burt Rutan, in 2003 as a design engineer. His early work included engineering contributions to SpaceShipOne, which won the Ansari X Prize in 2004.[4] He was part of the team awarded the Collier Trophy in 2004 for their work on the spacecraft.[5]
He advanced to Vice President of Engineering, where he oversaw the development of the Firebird demonstrator and SpaceShipTwo.[2] In 2015, Diachun was appointed President of Scaled Composites. During his tenure as president, the company conducted the first flights of several experimental vehicles, including the Model 401 and the Stratolaunch, the world's largest aircraft by wingspan.[4]
Pivotal
In 2019, Diachun left Scaled Composites to join Opener (later rebranded as Pivotal), a startup backed by Larry Page focused on eVTOL (electric vertical take-off and landing) technology.[4] He served as President and later Chief Executive Officer. Under his leadership, the company continued development of the BlackFly, a single-passenger personal aerial vehicle.[6]
Supernal
In 2021, Diachun was appointed Chief Technology Officer of Supernal, an independent company within the Hyundai Motor Group dedicated to developing electric air taxis for urban air mobility.[7] At Supernal, he led the engineering and technical development of the S-A2 eVTOL vehicle concept, which debuted at CES 2024.[8][9] He served in this role until 2024.[1]
Affiliations and recognition
Diachun serves on the Board of Directors of the Experimental Aircraft Association (EAA) and the General Aviation Manufacturers Association (GAMA).[10]
In 2014, he was named to Aviation Week & Space Technology's "40 Under Forty" list.[11] Purdue University recognized him with the Outstanding Mechanical Engineer Award in 2019 and as a Distinguished Engineering Alumnus in 2023.[12]
