We normally call that 'flying'

  Things don't normally fly at 7000 m/s. I wish them the best luck, but this is an odd project. And it's not clear it's saving any fuel or rocket structure.

    It *may* work if you had some impressive wireless energy transfer, but that means you probably would not actually save any cost in the grand scheme of things. Blimps sound like they should be good for space, but as a concept they're oversized and full of hot air unfortunately.

      if you're high enough they don't need much air in them at all
