Companies impatient to make drone deliveries a viable reality should have a win to celebrate soon. On Monday, Secretary of Transportation Elaine Chao announced in a “sneak preview” that her department would move forward with plans to remove waiver requirements for two key drone operation circumstances: flying after dark and flying over populated areas.

“First, at long last, the Department is ready to issue for comment a proposed new rule that would allow drones to fly overnight and over people without waivers, if certain conditions are met,” Chao said.
