“Nineteen years ago, I drove the Amazon packages to the post office every evening in the back of my Chevy Blazer,” Bezos writes in his latest annual letter to shareholders. “My vision extended so far that I dreamed we might one day get a forklift.”

 

But since then, Amazon has gotten a little more ambitious. After many critics (including us) derided his announcement late last year that his company was testing delivery drones, Bezos also used his letter say that the company is doubling down on this wildly ambitious project. Not only is the delivery drone program happening, but according to the CEO, it’s well underway. “The Prime Air team is already flight testing our 5th and 6th generation aerial vehicles, and we are in the design phase on generations 7 and 8,” he writes.
