A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (Vertical TakeOff and Landing) aircraft cannot perform.

The English word helicopter is adapted from the French word hélicoptère, coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix (ἕλιξ) "helix, spiral, whirl, convolution" and pteron (πτερόν) "wing". English language nicknames for helicopter include "chopper", "copter", "helo", "heli", and "whirlybird".

Whether it's a blend of Latin American and African cacao, or a single-origin bar, the process for making chocolate is essentially the same. And it starts with the tree, pod and bean...
