Overair, Hanwha Systems, and Jeju Province Unveil Collaborative Plan for Advanced Air Mobility Ecosystem

The Tri-Lateral Memorandum of Understanding Initiates Strategic Development of Public and Medical Advanced Air Mobility (AAM) Operations on South Korea’s Jeju Island

  • Inclusive Collaboration: Parties to work closely on various AAM ecosystem aspects, including infrastructure, manufacturing, training, maintenance, repair, and operations (MRO).
  • Public and Medical AAM Operations: The agreement encompasses the development of both public and medical AAM operations on Jeju Island.
  • Carbon Neutrality Alignment: The initiative supports Jeju Island’s commitment to becoming carbon neutral by 2030, offering environmentally responsible transportation options.

SANTA ANA, Calif., Oct. 17, 2023 — Overair, an emerging global leader in advanced air mobility (AAM) and developer of all-electric vertical takeoff and landing (eVTOL) aircraft, today announced it has signed a Memorandum of Understanding (MoU) with Hanwha Systems and South Korea’s Jeju Special Self Governing Province to establish and lead an advanced air mobility (AAM) ecosystem in Jeju, the largest island in South Korea and one of the country’s main tourist destinations.

The parties will collaborate closely on all aspects of the AAM ecosystem, including infrastructure, manufacturing, training, and maintenance, repair, and operations (MRO). This agreement also includes the establishment of a cooperative plan to develop both public, medical, and tourism AAM operations on the Island.

“Jeju Island is a beautiful resort destination, and it’s an ideal hub for advanced air mobility given its geography and its ambition to become carbon neutral by 2030,” said Ben Tigner, CEO at Overair. “We look forward to collaborating with our partners at Hanwha Systems.”

Jeju Island is an important tourism, green energy, and ecological province for South Korea. The island is currently preparing to become carbon neutral by 2030—producing all of its energy needs from renewable, zero-emission sources. Jeju Island is also a registered biosphere, with unique geography and ecology that draws tourists from across the world.

“We’re excited to partner with Overair and Hanwha Systems, ushering in a new era of sustainable and innovative transportation for Jeju Island,” said Oh Young-hun, Governor, Jeju Island. “This collaboration supports our 2030 carbon neutrality goal, enhances tourism, and provides employment for our community, paving the way for a greener and more connected future.”

About Overair

Overair is positioned to be a global leader in advanced air mobility. Spun out of Karem Aircraft in 2020, the Santa Ana, California-based company announced the design of its vehicle, Butterfly, in 2021. Butterfly is a breakthrough electric vertical takeoff and landing (eVTOL) aircraft. Butterfly’s proprietary technologies, derived from the Overair team’s decades of aerospace experience, create critical power reserves using today’s commercially available battery cells, which translate into advances in safety and a superior experience for riders and communities. With eVTOL adoption set to revolutionize aerial mobility, Butterfly is positioned to set the bar on real-world dependability, with best-in-class payload, sound emissions, and weather capability. Overair has operating partnerships with companies such as Hanwha Systems and Bristow Group, and the team completed its full-scale propulsion testing in the second quarter of 2022. Overair’s full-scale prototype is in its final assembly and will begin flight testing in 2024.
