You'll come to a section where you enter a Hornet, and are asked to destroy two scarabs. Destroy the scarabs but do not exit your hornet. From this location, you will want to fly up the spire and land high up on the left hand side on a metal beam. Once on the beam, you'll have to walk up the ramp to the very end of the beam. Here you will hear the music begin to play, and the achievement will unlock.
