It is safer the upper limbs (44.5%), followed by the lower limbs to fly over level ground because there are (32%), the back (9.8%), the head (7%), the pelvis fewer obstacles, the thermals are not too http://bmjopen.bmj.com/ (3.1), the chest (2.7%) and the abdomen (0.7%) strong, and winds are generally steady.

The engine caused 43 accidents (11.2%) in Furthermore, PPG differs from paragliding our study and was responsible for the majority of because the thrust of the engine allows the injuries to the upper limbs.
