Together, they bring decades of operational experience that will help support the future adoption of advanced air mobility.

Christophe Lapierre, CEO of Sigma Air Mobility, said:

"The transition to advanced air mobility will require collaboration between experienced operators and leading aircraft developers. Vertical has established itself as one of the industry's frontrunners, with a category leading aircraft. This strategic agreement takes us beyond the aircraft, furthering a vision to democratize air mobility while providing the ecosystem to support it. We look forward to working together to help prepare the next generation of electric flight."

Vertical has approximately 1,500 pre-orders for Valo from customers across four continents, including American Airlines, Avolon, Bristow, GOL and Japan Airlines.
