If Uber wants its flying taxi service to become a reality, it’s smart to deepen its relationship with a government agency that routinely handles logistics for ground-to-air traffic. That’s why Uber has signed not one, but two agreements with NASA to stimulate the growth of its flying taxi program. The first agreement will lead to creation of an air traffic control system to handle its aerial taxi fleet. The second agreement, which was announced this week, will give NASA the right to take Uber’s plans and simulate how they’ll work in Texas airspace.
