TSA -- More to come for GA...

Here we go again, it seems. Recent blurbs from various sources and reports indicate that our friends at the Transportation Security Administration are working on plans for "more robust" security oversight of general aviation -- both in larger aircraft like mid- and large-cabin business jets, fractional and corporate operators and...shoe drops here -- general aviation airports.

According to some reports, the work underway includes an effort to develop a standardized security assessment tool for GA fields and requirements and grants to bring those fields up to the standards that haven't yet been proposed or codified.

Once again the question comes up: exactly what GA threat is TSA -- and some members of Congress -- trying to solve?
