These SPJs provide fast, comfortable transport for the members of Spectrum and their equipment. The roomy cabin can quickly and easily be converted from normal seating arrangements to a VIP lounge, a cinema or conference room as readily as a personnel carrier. Based on design refinement of Universal Aero Engineering’s TVR 24 (2066), The SPJs are armed with air-to-air missile emplacements, but are also often escorted by the Angels on dangerous missions, and are powered by twin re-heat excess, air-ramjet, turbo-fan jet-engines, with Vertical Take-Off and Landing (VTOL) systems via retro-thrust Vilta air-brakes. These SPJs are 78 feet long, have a 37 foot wide wing-span, weigh 630,427 lib (281.44 tons), have a flight ceiling of 40,000 feet (height of Cloudbase) and a top speed of 1,125 MPH (supersonic, Mack 1.46). The rear-wing assembly can turn through 90 degrees, to a vertical position, to act as an air-brake when landing. The SPJs are nine seater vehicles (two persons as pilot and co-pilot, with seven as passengers), constructed at the Universal Aero Engineering Plant at an unknown location. All Spectrum vehicles use a special form of fuel of which every drop is distilled from the Spectrum ultra-sonic refinery at Bensheba, with a 500 gallon fuel capacity and 40 MPG limit, giving an SPJ a range 0f 20,000 miles without refuelling. The passenger jets are made of hardened Fleetonium alloy and have a hull, the lower half of which is silver in colour with blue on top separated by red stripes. These passenger jets are also fitted with triple hydrofoils projecting from the wing-stubs allowing landing on water, and autopilot system.
