French scientists rigged a plane for a special operation that would defy gravity. The plane performed swooping maneuvers that simulate low-gravity so the doctors can gain a better understanding how surgery can be done in outer space. Their tools used magnets to stay in place while the patient was under a special tent.
This is the first time that this has been done. The reason for this test is more than just a feasibility study since there could be spin-off benefits for health care. It looks like the next test will use a remote controlled robot to perform surgery.
