As always the wonderful R4 Cabin Pressure by John Finnimore got there first in Douz...
MARTIN (pilot) : We don’t pay for that!
JUTTEAU (airport manager): Then who pays for that?
MARTIN: Nobody pays for that! It just happens.
JUTTEAU: I don’t know what your fire trucks do, Captain, but our fire trucks do not just ’appen.
CAROLYN QANTAS: How much?
JUTTEAU CBR: Twelve thousand, three hundred and six dollars. But let us call it twelve thousand.
MARTIN Pilot: Yes, well, nice try, but that’s entirely illegal.
JUTTEAU: That’s debateable.
MARTIN (hurriedly): Unfortunately we don’t have time to debate it. Must be off now. See you in court – maybe.
JUTTEAU: Of course, what is not debateable is whether it is illegal or not to take off without clearance from Air Traffic Control. It definitely is.
MARTIN: Who’s gonna stop us?
JUTTEAU: No-one is going to stop you, but when you get ’ome, your national authorities – whom I would notify – would immediately suspend your operator’s licence.
(Sound of vehicles pulling up outside the plane.)
JUTTEAU: Also, I was playing for time. I am going to stop you, by parking the fire truck across your nose – although, on the up side, this time I will not charge you for mobilising it!
