Heard on HQPTC/RAFSC 'Quiet frequency' when my instructor was laughing at my aeros sequence(!) in a JP5
"Practice Pan (x3) - CWL xx, Practice pan, JP, 5miles north of Louth blah, simulated engine blah, request steer for Cranwell blah"
My Instructor " Roger CWL xx, London Mil, your Practice Pan is acknowledged, steer 380 degrees for Cranwell"
"Roger London Mil, turning left 380...................uh?"
Sadly for the stude, he never really saw the funny side and eventually got 're-roled'.
