How does the plane do a roll if it is really fast?
A fast moving plane will roll the same way a slow moving plane rolls. An airplane rolls by moving the ailerons on one wing up and the other wing down. The less stable an airplane is, the faster it will roll. A fighter jet is designed to roll much faster than a passenger airplane. The two biggest design features that affect this are where the wings are attached to the plane and how the wings are angled. The lower the wings are on the fuselage, or the body of the plane, the less stable the plane is. This means it will roll faster. A good example of a low-mounted wing aircraft is the Messerschmitt Bf-109, which was a German World War II fighter. Its wings were mounted at the bottom of the fuselage of the plane. This is the opposite of the Cessna 152, which is a small, civilian plane. If the wings are angled down (so that they point towards the ground) once they are attached, like on the Harrier jump jet, this will also make the plane less stable. Again, this will make the plane roll faster. These design features will help the ailerons make the plane roll faster.
