It is well known that after Podkletnov released info about his experiment, the US Gov became very interested. What i find puzzling is that they didn't follow his protocol, despite his warnings that they were deviating and it would change results. It makes me wonder if their public attempt at his technology was a sham, meant to discredit him. Since this has happened, Dr. Podkletnov has grown VERY quiet. Not what you would expect from the first person to publicly announced that he has reduced gravitational effect.
