Yep, there is a big training school there at the old international airport Marka. Looks to be a very good set up along the lines of uniformed cadet type schools.
Interesting and very mixed activities there - unusual to be able to go gliding within a city's boundaries. Worth persevering with further research - corny old phrase but they are very 'airminded' in Jordan. My only caveat is holding times and delays due to mixed military, civil, school and gliding activity in a procedural environment fairly close to the big Queen Alia airport.
