Quiet gliding in about 15'000 ft. Very calm flying in wave lift close to #Montagne-de-Lure in #SouthernFrance - lift and flying in wave lift is always super impressive 'cause the airflow is completely laminar. No turbulence. Very quiet other than the chit-chat on the radio. #silentsunday #sonntag #gliding #soaring #Segelfliegen #soobock
