Amazon.com AMZN -0.37% appears to be taking small steps to develop its drone delivery program and doing so from backyards in its hometown of Seattle.

On Thursday, one observer tweeted that the online retailing giant would be scoping out his property for its Amazon Prime Air program next week.

“Amazon is coming to my house to scan my backyard for Prime Air drone delivery next week!” wrote Andru Edwards, a Seattle resident who heads up a tech review site, on Twitter. Edwards is also an Amazon video personality, who appears in short online films for the company.

An Amazon spokesperson declined to comment. Edwards did not immediately respond to emails asking for comment and he deleted his tweet after FORBES contacted Amazon for comment.

While those close to the company say that Amazon Prime Air is far from being at a stage where drones can deliver packages to consumers, Edwards’ message indicates the company is laying the groundwork and doing research to move the program forward. Last month, FAA Deputy Administrator Michael Whitaker testified before congress that his agency expects to have formal regulations for commercial unmanned aerial vehicles (UAVs) within 12 months, and the company has said it’s determined to be ready as soon as those regulations are approved.
