Check out the video below to see where and how you complete ALL 15 of the Knife Flight aerial challenges. When you have completed them ALL successfully you will get the 'Close Shave' Achievement. Completing the aerial challenges is also required to reach 100% game completion. To learn how Knife Flights work, visit the Flight School at Los Santos Airport. They can be performed in a fighter jet from Ford Zancudo or a stunt airplane that occasionally lands at the airport in the desert. It is advised that you max out the 'Flying' attribute for one of your characters so you have more control over the aircraft you use and if it gets badly damaged just quick save and immediately reload the game to repair it.
