Mesothelioma is a type of cancer that typically appears in the lungs as well as the abdomen. This type of cancer was considered extremely rare until industries began using a fibrous material known as asbestos back during the 20th century. This material was once commonly used as a type of insulation since it was known to be both fire and heat resistant. Unfortunately, after a period of investigation, it was found that people who developed mesothelioma all had one thing in common. They had been exposed to asbestos.
Simulators have been used for decades for training commercial and military pilots. These machines were once extremely expensive, requiring a tremendously sophisticated installation that was used in such applications as training pilots on complex, multi-million dollar jets, where savings on jet fuel and the risk of loss of aircraft, made them cost effective.
