Amazon’s MK30 drones had been delivering packages in College Station, Texas, and Tolleson, Ariz. after the company won FAA approval in October.

The two flights, United Airlines Flight 1724 and Delta Air Lines Flight 1070 came too close to each other while arriving at the airport.

The Federal Aviation Administration is investigating after a United Airlines flight and a Delta Airlines flight had a near-collision over Phoenix on Saturday.

The close call between the United and Delta flights at the Phoenix airport comes amid an increase in plane near-collisions.

The planes, carrying more than 350 people, experienced "a loss of required separation" while preparing to land at the same Phoenix airport, the FAA said.

Amazon halts drone deliveries in Texas and Arizona, citing possible safety concerns with its MK30 drone software.

Amazon has paused drone deliveries after a crash at its test site in Oregon. However, the company says this isn't the main reason for the pause.

The Federal Aviation Administration is investigating a narrowly missed midair collision between a United flight and a Delta flight at Phoenix Sky Harbor International Airport on Saturday, the agency said.

An Amazon spokesperson said an incident that involved a crash at a testing facility in Oregon was not the primary reason for the pause.

A United Airlines 737 MAX 9 jet hit a coyote during takeoff on Sunday. It wasn't the only flight incident involving United over the weekend.

At this juncture, it should only take a few more months for the final assembly and flight certification paperwork to be finished.

The e-commerce industry continues to surprise with its ongoing transformations, particularly in the area of logistics. Recently, Amazon temporarily suspended its commercial drone delivery operations in Texas and Arizona after two of its latest MK30 models crashed at a testing facility during light rain.
