You learn something new everyday.
Globe.adsexchange is a aircraft flight tracker. In normal mode it shows all commercial, government and military flights, but if you click on the [U] button upper right corner it eliminates all commercial and private aircraft and shows only Government and Military aircraft that are squawking their position. Not all military and Government aircraft will show up only those who basically don't care if people know where they are. Fighters and bombers on patrol almost never will let anyone on a public site know where they are. A lot of training flights and cargo aircraft on the other hand will show up.
I was looking at military aircraft movement in the E.U. and spotted four French Pilatus PC21 trainers off the east coast of Corse. They are two seat single engine propeller driven trainers.
