This is an editing mistake. --- About the self balancing weight on top of the gyro: A gyroscope can drift to it's home position over time due to the self balancing weight. The drift is (luckily) very slow. If a gyroscope is placed upside down, after a while the gyro will drift to 'normal' position due to the self correcting mechanism affected by gravity. Since a plane is usually flying straight forward, the self correcting mechanism doesn't affect the reading. Well, the curvature of the earth than the self correcting system so the horizon is always matching with the curvature of the earth. If a plane would fly upside down for a very long time, the gyroscope will drift to it's 'normal' position. Under no
