Chartered airlines exist for a reason. Many wealthy travellers—and football teams—need to fly at odd hours or at short notice. Sometimes, as with sports clubs and business delegtions, large groups must travel together. Commercial airlines cannot always provide that service. Yet chartered and private flights are substantially more likely to crash, with pilot error being the cause in nearly 90% of cases. A Bloomberg News review last year found that private crews are overworked and demands from hurried passengers to land on time can encourage reckless decision-making. Lamia Airlines flight 2933 is another reminder of the horrible costs that people risk by cutting corners in the air.
