Sometimes archaeologists can see more from far away.
Barry Kemp describes how the Egypt Exploration Society got a bird's eye view of Amarna: "Most ancient sites being essentially flat make better sense when viewed from above. Ingenious measures for achieving this view are part of the history of archaeology, going back as far as photographic kites used between 1912 and 1914. We began at Amarna with kites, but found ourselves beaten by the weather. Either the wind is so strong that it raises the dust and obscures the ground, or it is too weak to lift the kite and its payload. We have moved on to a hot-air balloon, though not yet one of the giant ones which will take people aloft."
