M5320 Glassing-Reversal Terraforming Aircraft

The M5320 Glassing-Reversal Terraforming Aircraft, affectionately known as "Big Gerta" is a flying wing aircraft developed for reversing the plasma bombardment of a planet and returning its ecosystem to its former glory.

History
After the Covenant glassed several worlds and killed trillions, the UNSC decided they wouldnt stand for it anymore. Project "RebirthEcoX" began, and after 5 years of testing aerial terraforming technology, many iterations of the aircraft were drawn out. A flying wing design was chosen due to the fact that they are wider than conventional aircraft and could cover more space. Gertas went into production, and they were successful: multiple worlds originally thought permanently uninhabitable eventually and gradually were returned to their former state before they were glassed.
