Not sure if this will be of interest to anyone in the UK...
But at 9pm tonight a new series is starting on Pick TV, which is a "fly-on-the-wall" documentary about the day-to-day runnings on LGW and the refurbishment of the airport, called Inside Gatwick.
This programme is likely to be a re-run of something shown on one of the other Sky Channels as this is usually the way Pick TV works, but for people who have not seen it, maybe of interest.
Freeview - Channel 11
Virgin Media - Channel 180
Sky - Channel 152 or Channel 153 (+1)
