Oktas8,
Haven't laughed at a post so much in along while - particularly liked the "look up for the first time...." line, nice :-)
Had a stud once who was shambling through his left to right checks, got to the radio and had a complete coggie. He was just supposed to turn it on and then carry on (coming back to it after engine start to call for taxy). But he 'jumped a number of lines' and called for taxy.
ATC duly gave him taxy clearance and he motioned to the marshaller to pull the chocks - the marshaller looked quizically at him, but did what he was told - putting down the fire extinguisher first (hint number 1).
Student dutifully checks left and right, mumbles 'engine instruments all in the green' and advances the throttle. Strangley, the aircraft does not move forward - so the throttle moves further forward, still nothing (hint number 2 was the stationary propeller in front of us).
It was too much to bear, so (reverting to my training) I tried hinting:
"It's a bit quiet in here D*** isn't it?"
The defeated moan from the front indicated the penny had now dropped.
He went on to fly heavy metal.
