The first PAL-V One models are expected to become available in Europe in 2016 and in the United States by 2017. These models will cost between $350,000 and $650,000, and the first 50 models will be special edition. The biggest challenge is safety. Sophisticated autopilot programs are planned to ensure that the vehicles will fly themselves, be able to detect restricted airspace and enable non-pilots to maneuver through the sky without issues.
