Banshees, Fast and Low

Banshees, Fast and Low is a Campaign Achievement in Halo: Reach. This achievement is awarded when a player hijacks a Banshee in Campaign. It is represented by the traditional skyjack medal icon. The Jetpack is very useful for completing this achievement. Banshees can also be stunned for a short time with an overcharged Plasma Pistol shot and a Grenade Launcher shot.

Not all areas have Banshees that can be hijacked (such as the ones in Winter Contingency, where the Banshees don't have pilots). Good areas to achieve this are past the EMP barrier and before the spire in Tip of the Spear and within the caverns in The Package.

Trivia

 * The achievement's name is a direct quote from a Pelican pilot in the Halo 3 Campaign level Sierra 117.
 * This achievement is glitched, in that you can get it by boarding a Falcon. You first have to betray your allies such that they become hostile. Then go to an ally on a Falcon and you should get the option to "board enemy Falcon". Boarding it will award you the achievement.
