The Longsword fighter is an awesome, badass fighter aircraft that only appears in cutscenes because Bungie were too busy sucking each other's dicks to make it flyable. One day, shortly after the release of Halo: Custom Edition, a person called Tiamat created a map called Hugeass, it had Jets, Missle Warthogs, Pelicans, Japanese crabs and realistic Scorpion Tanks (they look something like this, I'm not joking) and most importantly, Longswords. It shocked the community and defined Halo: Custom Edition forever.
It has infinite rockets of pimpiness and a nuke Gruntiness charges to deal with any thing it want to mutilate. Longswords are very similair to the medusa head as everything that sees it basically dies.

SUPER AWESOME CRAZY MEGA UBER PWN SHIP
