All Airliners and space vehicles MUST have gyroscopes that hold their
planes of rotation to the surrounding stars.
Gyroscopes exhibit the 23 hour, 56 minute and 4 second period of
rotation that it takes the earth to rotate once in space (in relation
to the stars). This is known as one sidereal day in nautical almanac
terms.
