Reviewer 2 Report
My recommendations for improving the article:
Missing space between text and references, for example in lines 28 and 53.
In line 71, after the text wind disturbance, I recommend adding: (including horizontal and vertical gusts)
In the text, for example, in lines 110, 111 and 112, you use the term controllable ropes. But in Figure 1 you used the term control line. I recommend using the term controllable rope in Figure 1 as well.
Table 1 shows the data 12.8m for Length of suspending ropes. I think that is the wrong figure and it is too much for a parafoil with a span of 2 meters, chord 0.8 meters and an area of canopy of 3 square meters.
In line 259, I recommend adding units for the size of simulation environment: 500 x 500 x 500 meters.
