Borders of the Sky
The Mjolnir is a large battle zeppelin that was originally owned by Don Angelino of the Alliance.
Don used it to attack Perry Station, but failed and it fell into the hands of the Rocky Mountain Police Department, and was then confiscated by the Federal Bureau of Investigation.
After the Federal Bureau of Investigation was ordered to leave Colorado, the Mjolnir was turned over to Stan Clarke, who gave it its name.
The Mjolnir is heavily armed and armored. Its undercarriage is nearly impenetrable, and even the canvas is hardened and can withstand bullets or even rockets. It is armed with a half-dozen large broadside cannons (three on each side), six .30 caliber turrets, and hangar space for six small aircraft. It has a dozen engines and a top speed of around ten miles per hour.
