A group of Cambodian students are testing a prototype manned drone designed to ferry humans. Developed by students at the National Polytechnic Institute of Cambodia, the “NPIC Human Carrier Drone” is in the early stages of development and testing. The prototype can carry just one person weighing 60kg, and fly as high as 4m for just 10 minutes. Students have taken three years and $20,000 to build the drone. They estimate they need at least two more years before it’s completely ready and fully tested. The school plans to build a drone prototype focused on fighting fires.
