We've seen several attempts at making jetpacks that fly, but over at Arizona State University, a team is developing one for those who prefer staying closer to the ground. The DARPA-funded project (naturally) is called 4MM or 4 minute mile, and it aims to develop a jetpack that can provide soldiers that extra boost needed to run a full mile within four minutes. Sure, soldiers are physically fit, but the jetpack will make sure each one can do a 4-minute mile, even if they're not particularly fast runners, and even if they're carrying heavy equipment and armor.
Thus far, testers have been shaving seconds off their running time even while carrying the 11-pound jetpack, though the ASU researchers still have a ways to go to achieve their goal. Since being able to move fast without much rest can save your life in the battlefield, Harvard's Soft Exosuit inventors should totally get together with these ASU researchers to make the ultimate getaway suit.
