Sept. 12 (UPI) -- Two California-based tech firms on Friday joined a Federal Aviation Administration pilot program meant to speed up the delivery of advanced air mobility vehicles, commonly known as air taxis, the agency said.

The Electric Vertical Takeoff and Landing Integration Pilot Program will include at least five separate projects, the FAA said in a statement.

Both Archer Aviation and Joby Aviation are joining the public-private pilot program. The companies are primarily focused on electric vertical takeoff and landing technology.

The goal of the pilot program is to "form public-private partnerships with state and local government entities and private sector companies to develop new frameworks and regulations for enabling safe operations," the FAA said in the statement.
