Overheard on Salzburg tower a couple of years ago (paraphrased from memory) ...
Cessna 150: Salzburg Tower, xxx, overhead Hallein at 4000, inbound your airfield.
Tower: xxx, continue to Glasenbach.
Two minutes later
Chopper: Salzburg Tower, yyy, overhead Hallein at 3000, inbound your airfield.
Tower: yyy, continue to Glasenbach.
30 Second later:
Tower: OExxx, a helicopter will - how shall I put it? - undertake you in a few moments.
Servus from Salzburg
