During the months following my last article, “3D Printing and Drones,” there’s been many news events published regarding drones showing up in unexpected places. For example, a day after my first article was posted, a drone landed on the White House grounds. In March, ten drones were spotted mysteriously flying over Paris. There have been close calls between drones and commercial aircraft, reports of drug smugglers using drones along the US and Mexico border, and even reports of drones smuggling contraband over prison walls. On the other hand, you can find many examples of good uses for drones such as one Rhode Island teenager who hand-built his drone to help firefighters determine the cause of fires in buildings that are too unsafe to enter. He volunteers his time as needed to his local fire department.
