I'm not sure if that's ever been tried, but it certainly won't work for SpaceX. The landing system has to be able to work on any solid, flat surface in the solar system, such as the surface of Mars. There are no force fields on Mars. Edit: Every thread on HN or reddit usually has people suggesting other methods of landing rockets that require huge, specialized infrastructure. The primary goal here is to land on Mars without large or complex infrastructure. So even if you think you can devise a cheaper or 'better' system, if it doesn't work on Mars, it doesn't work at all.
