Project Excalibur: In a close parallel in the 1960s a secret research program by their world's Britain attempted to develop a working interface between the human brain and a new kind of computer. It didn't work especially well. Most subjects didn't react at all. But then one of them just disappeared, only to reappear a few minutes later skewered with a sword. After a few dozen duds another subject disappeared, only to reappear hours later having been struck with some kind of incendiary attack. Comparing the brains of the two anomalous results, they managed to determine the unfortunates shared a structural oddity and began to search for more people with the same trait. This time they would only use the fittest subjects, and only after intensive training in wilderness survival, martial arts, and stealth operations. And some of them started to come back alive even after weeks in the other worlds that their Jumper ability was sending them to. The Project's objective settled on one simple goal.. Find worlds with more advanced technology and bring back knowledge of it, or ideally samples. While starting subjects had no cargo capacity at all, experienced subjects began to demonstrate the ability to leave and return with objects. And other cross time factions began to get reports of mysterious men and women who would appear naked or scantily clad on some kind of espionage mission...
