Grace: Towers of Silence in India, it's uhh, it's where the Parsi bury their dead or don't bury their dead, actually.
Spence: What do they do?
Grace: They carry the corpses to these towers, which are stone, and in the centre there's a pit. They lay the corpses around the pit for the vultures. Now the Parsis believed that the dead are in a dangerous state of inpurity so they can't pass through soil or fire to the other world for fear of polluting the earth.

Boyd visits the freight terminal, apparently at London Heathrow Airport. In the background, a Ryanair plane can be seen on the tarmac - Ryanair do not fly into or out of London Heathrow Airport.
