The Egg Jet was used when Dr. Eggman escaped from Wing Fortress to the Death Egg after he failed to defeat Sonic the Hedgehog in the Wing Fortress' cockpit room. While Sonic missed the Egg Jet, Tails returned with an enhanced Tornado, and they chased after it. After a while, Sonic managed to grab onto the Egg Jet's side and rode it to the Death Egg where it docked. Since the Egg Jet has not been seen since then, it is possible it was destroyed when the Death Egg crashed on Angel Island or when the Death Egg was completely blown up. (VG: StH2)
