Amazon, who announced their intention to explore drone deliveries, has now received the go-ahead from federal authorities to start experimenting.

The Federal Aviation Administration issued an “experimental airworthiness certificate” to the company on Thursday, allowing the company to conduct research, development and crew training for unmanned aerial vehicle usage, the agency announced.

But there are caveats: the flight operations must stay 400 feet or lower, must be during daylight and within line of sight, and the person flying the drone must have a private pilot’s certificate – and a medical certification, the FAA said.

Amazon announced last year its intentions to get packages into customers’ hands within 30 minutes, through the drone program. Calling it “Amazon Prime Air,” the company sent a letter to the FAA in July 2014 saying it intended to get in the air as soon as possible.
