Take a car down the subway and then ride down the tracks until you see the words say Francis international airport then stop at the train station in the Francis international airport then park up against a wall with a box sticking out of it next park the car next to the wall and jump on the box walk slowly away and then jump into the glitch it will look really weird but that is a good sign that it will work it'll take a LOT of tries but it works .
