While I was planning on the Coastal sector last week :
Female SAS-pilot : "Maastricht, there is a constant noise on the
frequency...".
Controller " SASXXX roger,.... Speedbird xxx, do you hear interference as well ?
Speedbird : negative...
Controller : SASXXX, can you describe the noise ?
SASXXX : it sounds like " wee-wee-wee-wee " ( in a high pitched voice )....
We all bursted out laughing
Next call was " Sounds like my wife..." from another pilot. Hilarious...
