A Vogon Constructor Fleet is a group of yellow ships used by the Vogons to destroy planets. They hang in the sky in exactly the same way that bricks don't. The Hitchhiker's Guide to the Galaxy states that it is impossible to hitch a lift on a Vogon Constructor Fleet. However, Vogons employ Dentrassis as chefs on them. The Dentrassis hate Vogons, and frequently allow hitchhikers to come aboard. A Vogon Constructor Fleet is used to destroy Earth, and the same one is later used in an attempt by the Vogons to destroy the planet Nano. This particular fleet is captained by Prostetnic Vogon Jeltz.
