Fifty-degree Banshee fire
From Halopedia, the Halo wiki
For other Banshee glitches, see here
The fifty-degree Banshee fire is a glitch that may only be performed in Halo: Combat Evolved or Halo: Combat Evolved (PC port). A similar glitch to this one can also happen with the Ghost in Halo 2.[verification needed]
Although this is possible to do with the Banshee's Fuel Rod shot, it is not safe because the Fuel Rod has its own set of in-game physics and thus is affected by gravity. As such, it may sometimes hit the tree and damage the player.
