-## Task
-Develop an R-based software, which will perform the following tasks:
-
-1.  download from the OpenSky Network online database the observations of the trajectory of a randomly selected aircraft on a randomly selected flight over at least five days, in uninterrupted continuity (1)
-
-2.  perform the selections in the graphical user interface (GUI) of your R script,
-
-3.  determine the characteristics of each trajectory according to the parameters: diffusion distance, straightness, duration of travel, mean travel velocity and fractal dimension (2),
-
-4.  using the R library trajr, (4) perform basic statistical analysis of the parameters of daily trajectories from (3): arithmetic mean, variance, quartiles, boxplot, estimate of the density function of the experimental statistical distribution, analyze and interpret them.
