I just came across an ad for FlyClear.com, which is a private for profit company designed to help its customers get through the airport quickly. They are a voluntary, self-credentialing, private sector service. And if an airplane blows up because of their service they are probably insured and/or the owners can quickly cash out before the lawsuits strike. I find it fascinating that all of society has (apparently) arbitrary bottlenecks placed on it and then some for profit company can claim to create an alternate route for those who seek it.
