One more thing to be thankful for: a sensible response to the tragic airplane-helicopter crash over the Hudson River in August. As of this week the FAA has applied new traffic-separation rules for small airplanes, airliners, and helicopters flying above the Hudson that should reduce the risk of such a collision ever happening again. The rules codify what had been informal procedures for keeping aircraft out of each other's way. But they don't over-prescribe, regulate, or restrict. Here is the FAA's diagram of the new separation procedures:

Versus the chart of how confusion could arise under previous rules:

When regulators and security officials address a problem through minimal rather than excessive rule-setting and interference or panicky over-reaction, that is worth our thankfulness too. Building toward a crescendo of things to be thankful for at this time of year.
