As we expected, delivering packages to customers across these different environments provided valuable operational insights. For example, we knew that we’d experience more dust in the air in Phoenix than we would in other places. While we’d already designed the drone to be safe in those environments, the data from these flights still gave us opportunities to learn and build even more safety measures into our drones. One example of that is in an altitude sensor that we use: We saw that environmental factors like dust can sometimes interfere with its readings.
