Gravity Industries was started by Richard Browning, an engineer descended from a line of pilots and with personal experience in the Royal Marine Reserves. It's a strange name for a company dedicated to fighting the definition of their own name; the UK-based company manufactures and sells Iron-Man-like jet suits that allow individuals to fly.

After years of development, Browning's jet suit design--which first flew in 2016--is ready for prime time. Here's footage of Royal Marines successfully conducting a ship-boarding exercise while wearing the suits:

It's crazy how effortless it looks; it's also incredible that they can take off from the boat without torching it. I expected to see flames, not pure thrust, coming out of the jets.

If you'd like to travel out to Gravity's facility in Goodwood, UK, and if you've got £2,000 (USD $2,800) to spare, you can fly in one of their suits yourself.
