From Warhammer 40k - Lexicanum
Grot Bommers are small, lightweight Ork aircaft that are piloted by Grots and in battle can drop Grot Bomms or rokkit pack-equipped Stormboyz. The Bommers are usually deployed from larger Ork aircraft and their speed, combined with the Grot pilot's desperation to engage with the enemy, make them the perfect homing missile.
