There is a flight pack in the 4e book. (can't remember the name if it, as it was pretty silly)
And NO. The tech level is NOT there...... you have several large problems to overcome that the movies like to gloss over....
such as Fuel, The Exo-7 is the vectored Thrust engine, which means you need a liquid fuel..... Something the movies gloss over. You could use a battery system, but it would NOT be a vectored thrust system and more of Rotary turbine, which then means you blades like a helicopter... which means they would have to much bigger then the person to provide the lift needed....
OK, first off, would have responded earlier, but real life and junk.
Second, it would be helpful to back some things up with a little research/science, especially is you are quoting "real world" physics. Jet-packs have been in existence (though mostly as experimental/enthusiast craft only) since the '60's (though on paper as early as 1919). Specifically, liquid fuel and vector thrust is possible right now. True, sustained flight was approx. 10 min with kerosene fuel, but proof of concept.
Also, winged jet-packs have also been flown in this century, also made of carbon fiber. Again, these are all experimental currently, but with the advances in technology in SR, especially drone tech and ASSIST, as well as the possible para-military (read corporate) utility I think the possible push for the research is plausible.
Liquid fuel in Shadowrun could also mean an Electric Fuel Cell not necessarily jet fuel (or more like kerosene fuel in current models). For in game reference, in previous editions (specifically 3rd, Rigger 3) Fuel Cell was a possible power source for Thunderbirds and both Med and Large UAV vector thrust engines. Current technology has entertained the idea of adding jet turbines to a fuel cell engine to maximize potential.
Some things from other media just do not translate well to actual "real world" physics.... And keep in mind the Marvel universe also has "Gamma Radiated" people walking about, people with gigawatt electro magnet reactors in their chests, People that fly through space (and TALK in space) with out space suits.....
As for this? Yes, entirely appropriate to mention when you have peoples' DNA being triggered by an (scientifically) undetectable mysterious energy into genetically stable sub-races, where certain individuals have their consciousness leave their bodies for extended jaunts into other realms of existance only thought of in myth and legend and have the ability to bend modern physics to their, almost, complete control, as well as biologically improbable hexapedal super-predators with penchants for social manipulation and economics (among many other varied pursuits to include show business and teaching).
As I said, personally, I think the technology is just about there, especially for experimental models. My question was for some helpful input preferably.
Again, is there any precedence in the books (don't own Rigger 5 yet) for the handling to be based off of the Physical Limit or should something like this have a static Handling?
