We all hate these cameras when we get caught. But we know why they’re there. Just drive up the state’s many gorgeous and winding mountains. Cars break the 75-mile per hour limit – even to turn a curve, or when passing by a construction site.

The National Transportation Safety Board, the bodyguard of America’s transit, has pointed out for decades that high speeds can result in death. Shocker. Here’s one of many studies, in case you want details.

The Daily Show’s Olivia Munn just did a hysterical interview with AZ State Rep Carl Seel about it. He supports SB 1070. (For anyone who hasn’t read the news this year, that’s the controversial law requiring police to arrest anyone who they suspect doesn’t have immigration papers.)

But Seel draws the line with speed cameras. They are the eyes of Big Brother, invading our privacy.

Munn crinkled her brow, “So speeding is probable cause to check immigration status. But speeding is not probable cause to give you a ticket for…speeding?”

Precisely.

Arizona’s hurting for money, so it can’t afford to put cops on the highways to replace the cameras. Hopefully it can afford the stationary that officers use to write up accidents after people have gotten hurt.

Without even realizing it, our abilities decline once we fail to get our recommended eight hours of sleep. Response times, decision-making, reflexes, mental focus and mood all begin to slide once a human begins building a sleep deficit. All the while, the propensity for risk-taking increases. In short, fatigue and sleep deprivation can put even the most highly trained, qualified and experienced people in an irrational state of mind. As one expert told News21: “It makes them stupid.”

As we examine fatigue in the transportation industry, we’ve found that the NTSB has issued repeated recommendations to regulatory agencies across all sectors, some dating as far back as the early 1970s. These recommendations have largely been ignored.

In aviation, there is rarely, if ever, a single cause for an accident or incident. Often the circumstances are more like the links in a chain. Fatigue’s place in this chain is most often evident when something has gone wrong. It’s the decision or reaction to that first link in the chain where the real trouble can begin for a fatigued flight crew.

It was an element in the Colgan Air crash near Buffalo, New York that killed 50 people in February 2009. And it has been a factor in hundreds of other deaths over the years.

Yet little has been done to protect pilots, traffic controllers and the flying public from the one bad decision, on the one bad day a pilot or controller might have during an otherwise long and unblemished career.

The recommendations are fairly simple: Change the limits of flight and duty times for flight crews so that it takes into account modern research into sleep, fatigue and circadian rhythms.

While we wait for regulatory agencies to change the rules, a pilot is climbing in the cockpit after a fitful night of undiagnosed sleep apnea; or a controller peers into the glass of his scope with a few hours of sleep and a hot cup of coffee.
