Hello Guys and Gals, Very EASY Achievement here.
I start on the road side, as you see in the video, i go all the way to the "Jurassic park" bit, just before where the big bones are.
That way you can easily get 3 stars there, and again, i slightly take my time (Slightly), but i then end up going past the length of the runway to where the ramp is directly behind (Or infront, depending on where your looking) the runway fence, Gun it and you should nail it easy.
If your worried about stars and time, Pin the challenge which is the Red Brick, 8th one from the right on the bottom row!
Hope this helps!
