But, no, it has nothing in common with chupacabras.
Another clue that the jumping was done by wire is that a) they didn't have the metallurgical technology for this and b) they didn't have stabilizing gryoscopes. I have a friend who owns a pair of "jumper stilts;" basically leg extensions with powerful springs that CAN enable you to jump higher than normal.
He nearly broke his leg and his arm, and it was extremely unreliable on anything except a very smooth surface and in ideal conditions. Even after a month of practice, it was still a fairly dangerous (but fun) toy.
...and he wasn't jumping as high as Jack was reported to.
It would be extremely obvious if he was using wires, for one he would have to hang about in that area for a while setting it all up, and secondly after the leap he would still be attatched to all the wires and therefore wouldnt be able to go very far at all. Thirdly there aren't reports of pully's being set up in the areas where he was sighted
