From Halopedia, the Halo wiki
In 2552, Peterson was assigned to Pelican Echo 136 attached to the UNSC Pillar of Autumn. When that vessel crashed on Installation 04, Peterson and a few of his fellow pilots, including Flight Captain "Foe Hammer" Rawley, took their Pelicans and abandoned ship, effectively saving them from destruction. Peterson and Echo 136 then met up with other Human survivors at Alpha Base. He was tasked with hauling supplies from the crashed Autumn to Alpha Base along with the pilot of Echo 206.
Later, during the ODSTs' assault on the Truth and Reconciliation, Peterson and his Pelican landed troops in the launch bays of the ship. Peterson was killed in the destruction of the Truth and Reconciliation.
