The U.S. Federal Trade Commission filed a lawsuit against Uber on Monday, alleging that it enrolled consumers in its Uber One subscription program without their consent and made it too difficult for them to cancel the service.

Uber One members pay $9.99 per month or $96 per year for a range of services, including fee-free Uber Eats food deliveries and cash back when they take Uber rides.

In its lawsuit, the FTC said multiple customers complained that Uber signed them up for Uber One without their permission or charged them for the service before a free trial period was over. In at least one case, a person was charged $9.99 per month even though they didn’t have an Uber account, the lawsuit said.

A commercial airliner was on final approach to San Francisco’s international airport in November when the crew spotted a drone outside the cockpit window. By then it was too late “to take evasive action,” the pilots reported, and the quadcopter passed by their windshield, not 300 feet away.

A month earlier, a jetliner was flying at an altitude of 4,000 feet near Miami’s international airport when its pilots reported a “close encounter” with a drone. In August, a drone came within 50 feet of clipping the left wing of a passenger jet as it departed Newark International Airport.

The incidents were all classified as “near midair collisions” — any one of which could have had catastrophic consequences, according to aviation safety experts. They were also not isolated encounters.
