There is no doubt that a percentage of GA pilots are apprehensive of going near or taliking to Mil units. The, at times, high staccatto approach in delivery, and unintelligble high speed talk, can be off putting. On occasion I have been left wondering what on earth the controller had not only said, but meant. I have often wondered were the RAF pilots a breed appart in that whilst coping with handling a FJ they also had to decipher the instructions coming through the headphone.
I think this has been improving,with ATC open days, an appreciation of 'other' air users, but it definately still exists.
Benson always very helpful btw.
