X3 project by Eurocopter (french firm) has been unveiled a few years ago as a project. Today, this awesome project is … real and does fly! X3 is a nice hybridation between a plane and an helicopter. This combination allows the X3 to be a superfast helicopter, as you will see it in the video below, X3 can easely overtake a TGV lanched at more than 300 km/h on a french railway!
Hope you will enjoy this great and awesome video.
