Swift and Shallow
From Halopedia, the Halo wiki
Swift and Shallow is an achievement in Halo: The Master Chief Collection. It is awarded by hijacking a Banshee during the campaign in Halo: Reach, equivalent to the achievement Banshees, Fast and Low in the original release.
This achievement is easiest completed on The Package at Rally Point Bravo, using an EMP to disable a Banshee as it is attacking, and then hijacking it while disabled. Another method reported to work by some users is to betray Marines on Exodus at Rally Point Charlie until they turn hostile, then 'hijacking' the left chaingun seat of the awaiting Falcon.
