Since you asked me for a story about planes and fuel, I believe I have one....
DOUGLAS: Could you just double-check this fuel order?
MARTIN (taking the paper from Douglas): Er ... (high-pitched) What?! Three thousand litres? Why have you loaded three thousand litres?
OTTO: Because you asked for three thousand litres.
MARTIN: No I didn’t. I said, ‘We’ll need three thousand litres.’
OTTO: ... Okay, is that sounding any different to you, because ...
MARTIN: No: ‘We’ll need three thousand’ in the tank and we already have sixteen hundred, so ...
OTTO: Well, maybe I am a simple soul, but I heard, ‘We need three thousand litres,’ and what I thought was, ‘Oh, I know, I’ll give them three thousand litres! They’ll like that!’
MARTIN: Yes, but ...
DOUGLAS: Yes, well, whoever’s fault it is ...
OTTO: It’s his fault.
DOUGLAS: I know. But the good news, Martin, is we’re still under maximum take-off weight.
MARTIN: Oh, good.
DOUGLAS: The less good news is that when we get to Fitton, we’ll still be way over maximum landing weight.
MARTIN: ... Right. So we can go up but we can’t come down.
DOUGLAS: Exactly. We are Newton’s worst nightmare.
