This is an incredible development, but the real test will be what scale they actually manage. On that note: > Walmart announced an expansion to its DroneUp program, which it claims will provide the potential to reach four million US households ... as well as the ability to deliver more than one million packages by drone per year. It sounds like each household will only be able to receive one package every 4 years. They won't be putting Santa out of business just yet, then.
