Spent a while in the evening, watching military aircraft over Europe. 4 of them. A helicopter about 200ft below ground over Dublin, another over Paris, a US C-17, apparently returning to Ramstein from the direction of Egypt, and a Czech Gripen flying back and forth and up and down.
I was thinking the Gripen might do a practice intercept of the C-17 at 30,000ft but no. It went lower level and disappeared from view a little below 1,000 ft. No runways very near that location.
