10 eVTOL Development Programs to Watch in 2021

A list with the latest program developments for some of the top eVTOL aircraft makers in the world right now.

The last 12 months have featured some of the fastest moving technological innovation, regulatory, and partnership advancements toward enabling a future urban air mobility ecosystem where electric vertical takeoff and landing (eVTOL) air taxis will one day fly new purpose-driven mission sets across a variety of civilian and defense operations.

Considering the rapid pace that the companies building the actual vehicles, or air taxis that are to serve these mission sets over the last year, some have emerged as closer to making eVTOLs that were mostly computer-generated three-dimensional concepts and drawings a few years ago into a reality by the mid to late 2020s. In this article, we selected 10 companies that are developing VTOL aircraft that are all-electric, hybrid, and gas-powered with a plan in place for future alternative sources of electric power.

While there is no ranking order to the list, all of these companies are highlighted based on achieving recent major regulatory, technological or business-related program milestones associated with the VTOL vehicle that they're developing.
