Problem is that as soon as any producer thinks of anything to do with flying it has to be Heathrow. One reads in the papers of aircraft "contacting the Heathrow control tower" when it's over the Atlantic and other such nonsense.
I was involved in a similar programme from Heathrow about 30 years ago. Idiotic presenters trying to interview working controllers and producers running around saying "That's good TV", usually when someone had said something daft. During the week-long farce over 200 BBC staff entered the tower. Probably the best bit was when some of us entered the lift with one of the snotty lady presenters who objected when we pushed buttons for intermediate floors on the way down. Unbelievably she said: "Do you know who I am?" To which we replied "No". They really are a bunch of clowns and I'll bet there will be some cringing by Heathrow staff when they see the end product.
