Another nice mid-sized vehicle, the Jump Jet was one
vehicle that had actually appeared in the comics from
time to time, albeit not quite looking like this. This
concept art is cool because it features the Riddler, who
never made it into any official line-up for the collection.
Much like the Superman Glider shown elsewhere in this
article, the Jump Jet apparently needed the figure "flying"
it to lay down and be clipped onto the underside. Or maybe
it just rattled around loose inside the cockpit. But the
vehicle is too small to feature a pilot's chair inside.
It also would have had a nice set of folding landing gear
on the undercarriage.
