Overview: Toxic Flyer Pain Free Big Blue Death Defying Toxic Flyer For some people, flying is an anxious white-knuckle ride as they carry a pressing fear that the aircraft will crash. But there’s another risk that may be far greater, which affects us all. It’s called Aerotoxic Syndrome and it’s caused by breathing contaminated cabin air. Some experts are calling it the asbestos of the airline industry – it can result in a range of serious health problems, even death. But what’s most shocking is the way aircraft manufacturers and operators have known about the problem for years and have done nothing about it.

And, ironically, their condition just may lead to a breakthrough for those who suffer chronic pain.
