21. The other civilian personnel included Sperry Gyroscopic Company. 22. His routines include many high energy gyroscopic maneuvers. 23. Technology for both machines uses gyroscopic sensors and computers to mimic principles of human balance. 24. Thus gyroscopic precession is what makes the boomerang return to the thrower when thrown correctly. 25. Rotor tilt was controlled through gyroscopic precession. 26. In the 1960s gyroscopic orientation was introduced. 27. This rotation is not to be confused with the rapid gyroscopic rotation of a rifle bullet. 28. They are grouped according to pitot-static system, compass systems, and gyroscopic instruments. 29. Another contribution of gyroscopic effects is a roll countersteering, below, and the countersteering article. 30. In the game, players control a gyroscopic vehicle equipped with an array of multidimensional abilities.
