What is the thing on top of a helicopter called?

Can you fall out of a helicopter?
The centripetal force moves horizontally toward the center of the object around which it rotates, which is the cabin of the helicopter. The centripetal force keeps outer objects pressed inward toward the center. Along with centripetal force, soldiers avoid falling out of helicopters thanks to harnesses and straps.
Why do helicopter pilots sit on right side?
Most helicopters these days have a collective for each seat, located on the left, so the pilot wants to use the hand in the middle of the cockpit to work the radios and things. Hence, they sit on the right side, which places the collective hand in the middle of the cockpit.
