With Christmas comes gifts like hover boards and paintball guns that are highly desired but require skill to operate properly. An item sure to be a popular present this year is the unmanned aircraft system—commonly known as a drone. Drones, in the hands of new, untrained users, can be dangerous, and even when operated by experienced users they increasingly are causing accidents and injuries. https://www.faa.gov/uas/getting_started/
Drones cause accidents by dropping out of the sky or crashing into people and things. Collision with a drone, with its sharp angular parts, high speeds of travel and zooming in seemingly out of nowhere, naturally results in physical injuries and damage to whatever it hits.
Drones can malfunction for many reasons, such as an operator failing to correctly gauge speed, distance, angle, height, weather conditions, etc. A drone may unexpectedly lose power midflight. Also, a drone may have a defect in its design or manufacturing.
