We could all be witnessing a bunch of Tony Starks next summer and I'm absolutely here for it (and I would also like to have a jet pack plz&thx).
UK Company Gravity Industries have created a jet-pack for First Repsonders and you got to check out this vid out because it can definitely help save people's lives if they're out hiking, climbing, and any other outdoor activities.
Hopefully if their timeline is right, we can see jetpacks in the very near future!
