The InertiaQX5 was one the greatest fighter jets known to man. It was fiendish in the face of battle and faster than a speeding bullet. On its last airborne mission, the pearly aircraft disappeared. Rumor has it that the plane plunged deep into the sea, meeting a Neptunian fate with a lost watery grave. While the story of the InertiaQX5 has never been truly solved, the mysterious jet is still seen to this day. It circles around swiftly, leaving billowy white contrails as it vanishes into the clouds.
