Ibex,
You're a party pooper. And wrong. Last time I rang to give a departure report on my mobile (I couldn't get thru on HF or VHF despite being less than 200km from a major captial city: thanks Dick) the aeroplane did a gentle 90° turn. When I hung up, it immediately did a derry turn in the opposite direction (applying full power on the bottom motors, thank god) causing the cart tart who was standing in the doorway about to give me me cuppa to say "could I have one of those please!". So there.
