WASHINGTON, March 5 (Reuters) - The Federal Aviation

Administration said Wednesday that upgrading the aging U.S. air

traffic control system will require multiple technologies and

companies.

"That is why we are testing multiple communication

technologies, including satellites, fiber and wireless to ensure

the safety of the national airspace system. Beyond that, no

decisions for other deployments have been made," the FAA said.

Some Democrats have suggested the FAA could cancel a $2.4

billion FAA contract with Verizon and give it to Trump adviser

Elon Musk's Starlink unit.
