Some of humanity’s aspirations are timeless. Such is the desire to fly. As a result, the challenge is continually taken up by bright minds. As technology advances, our dreams of gracefully transcending the bounds of earth’s gravitation seem more achievable. Such is the case with Gravity, which produces one of the fastest jet packs supporting human flight today. It is inspiring to see dreams like this pursued. Not only because they make progress towards addressing our timeless fascination with flight, but they open up many practical applications.
