When I was about three years old I kept falling over, so my mum sent me to ballet classes in the hope that it might help my balance. Spoiler alert: it didn’t. It turned out that in the late 1980s, ballet lessons for children involved more running around in striped leotards pretending to be bees than any actual pliés or relevés. While I’m steadier on my feet now than I was in my insect cosplay days, my history of hitting the deck probably wouldn’t normally make me a prime candidate for learning to fly – but Richard Browning, jet suit inventor and founder of Gravity Industries, reckons he can teach pretty much anyone to do it in just a handful of tries. Has he ever encountered a gravitationally challenged, failed bumble bee before, though?
