Ppers...
How long does 10 seconds last exactly? 
A true story (for once)...and one which has nothing whatsoever to do with flying - like many others on this mil forum!!!
Whilst walking the corridors of power recently, I was collecting 'charity monies' for the London Marathon... a rattle of the tin and a brief conversation ensued about training, weather etc, when the following occurred:
I was asked, "How far is the marathon?" - not a bad question, to the uninitiated or running averse person and a response of "just over 26 miles..." wrapped it up. Or so I thought.
The next question flawed me: "How far is that?"
Was this a question of Einsteinian proportion or what?
There's a prize of 10 Lire for the best response.
