Air charter. Air charter is the business of renting an entire aircraft (i.e., chartering) as opposed to individual aircraft seats (i.e., purchasing a ticket through a traditional airline). While the airlines specialize in selling transportation by the seat, air charter companies focus on individual private aircraft and itineraries, urgent or time-sensitive cargo, air ambulance service, and other forms of ad hoc air transportation.
A political machine is a political organization in which an authoritative boss or small group commands the support of a corps of supporters and businesses (usually campaign workers), who receive rewards for their efforts.
By the 1960s, only a small number of political machines remained in the United States, largely in cities such as Chicago that had been able to escape full-scale civil service reform. Democratic Party reformers undermined these remaining machines between 1968 and 1972, though a handful still exist.
