OPENER Names Ben Diachun as Chief Executive Officer

Expanding Operations, Bringing BlackFly to Market

PALO ALTO, Calif., Jan. 14, 2020 (GLOBE NEWSWIRE) -- OPENER, a pioneer of aerial vehicles for consumer travel, is pleased to announce the appointment of Ben Diachun as its new Chief Executive Officer (CEO). OPENER is producing BlackFly, the world’s first fixed-wing, all-electric vertical take-off and landing (eVTOL) personal ultralight aircraft. Founder and former CEO, Marcus Leng, will oversee next-generation manufacturing and international operations as Chairman of the Board. 

“During this transformative time, there is no better person to guide OPENER than Ben Diachun,” said Marcus Leng, OPENER Founder and Chairman. “Ben is a proven leader in the aerospace industry, he gets things done, and he has the innate ability to inspire everyone around him. Ben has the technical proficiency and corporate know-how that OPENER needs as we expand operations, produce vehicles, and grow the company.”

BlackFly is designed to easily takeoff and land in small areas and travel distances of up to 40 miles at a speed of 80+ mph (US restricted performance: 25 miles/62 mph). The vehicles are simple to master and require no formal licensing (US only). 

“OPENER is pioneering a new industry with BlackFly. I am truly honored to lead the company into production, establish sales initiatives, and secure our market position,” Ben Diachun said. “We have the opportunity to show the world that three-dimensional transportation is real. A big part of my job is to seize this vast opportunity and successfully bring a safe and exciting flying vehicle to market.”

Since joining OPENER as company president in May, 2019, Ben Diachun has deployed his unparalleled engineering experience to improve manufacturing processes, enhance efficiency to meet future demands, and grow the company’s team. Ben comes from Scaled Composites, where he participated in key engineering design, directed flight testing, and stepped up into leadership roles.  Ben is recognized for taking 15 new aircraft types from concept to first flight in his 16 years at Scaled.

On October 5, 2011, history quietly was made near the small town of Warkworth, Ontario, Canada. That day saw the first manned flight of a fixed-wing all-electric VTOL aircraft. This event prompted the formation of a stealth company with the sole purpose of pursuing the development of this new unique technology. In September of 2014, the Company reorganized as OPENER and relocated the majority of its operations to Silicon Valley in California to pursue an unencumbered and accelerated development timeline.  Find videos and more information at
