A man has lifted the curtain on a part of the airport few people get to see.
If you are a lucky air traveller, a visit to the airport means placing your bag down on the scale at the check-in desk before watching it ride the conveyor into the bowels of the travel hub, reappearing on a similar belt at your destination.
If you're unlucky, the bag will go missing for several days before turning up at the same airport, as happened to many holidaymakers in the UK last year.
