Similar to several other Red Ribbon Army materials, it was kept within a Capsule. It also had access to rocket engines to allow him a speedy getaway. The anti-gravitational aircraft lacked any onboard weapons, was meant to be piloted by one person, and was meant for long-distance travel.
General Blue used this aircraft after taking the Dragon Balls and leaving the Dragon Ball Gang to die from a time bomb in order to escape with his prize. However, Goku, having evaded the bomb with help, proceeded to give chase, with Blue using the onboard rocket engines to both escape Goku and get him caught in the blast. The vessel was ultimately destroyed from a collision with a mountain, although Blue survived.
Video Game Appearances
The Thunder Rocket appeared in Dragon Ball Z: Budokai Tenkaichi 3 as part of General Blue's Ultimate Blast, Rocket Engine Spark. The cockpit in the cinematic for the attack is shown to be slightly larger than its depiction in the anime.
