Once the Andor team returned to Yavin 4, not only had they located the Death Star plans, but they also discovered that Imperial scientist Galen Walton Erso placed a flaw in its design, allowing for its destruction.

This group, composed of the Andor team and other Alliance special forces units, came to create Rogue One.
