Way back in the spring of 2017, NEWSREP reported on former British Royal Marine-turned-inventor Richard Browning and his efforts to produce a jet pack that allows the user to fly a whole lot like Iron Man — using thrusters mounted on different parts of the body to control his movements while airborne. Browning, the company that sprang up from those efforts, is in the news again, thanks to a demonstration of its latest jet pack conducted, appropriately enough, on the assault course of the U.K.’s Royal Marine Commando Training Center in Lympstone, Devon.

The latest iteration of Browning’s suit utilizes six small jet engines: two mounted on the user’s back, and two mounted at the ends of each arm. Previous versions used leg-mounted jets, but the shift in placement seems to have added some much-needed stability to the apparatus. This new demonstration doesn’t appear to be tied to any sort of deal brewing between Browning and the U.K. Ministry of Defense. Although his jet pack does make for one hell a ride, it likely wouldn’t offer much in the way of combat value in its current state. Of course, that didn’t stop some of the spectators from pointing out how handy a jet pack might be.
