Planespotting Putin, Musharraf and Nazarbayev

What do these three heads of state have in common? All have had their executive aircraft -- those luxury suites on wings on which they travel the world -- photographed and logged by amateur plane-spotters.

This is good fun. But these hobbyists can also break news. For instance, the latest issue of Foreign Policy has a piece about a possible six-year European shopping spree by Tunisian First Lady Leila Ben Ali. Tunisian bloggers have tracked the north African country's presidential aircraft all over Europe, while noting that reclusive leader Zine el-Abidine Ben Ali almost never leaves his office. They don't seem far from putting two and two together.

The on-line Foreign Policy piece considerately explains how to get started tracking the movements of presidential planes using sites such as Airliners.net. How about the aircraft used by Vladimir Putin? Or the plane used to fly Nursultan Nazarbayev? How about Pervez Musharraff's aircraft?

The movements of the presidents themselves aren't that interesting. After all, that's well-covered by the media. But it could be grist for trackers of first family wealth and spending habits.
