For any who might be interested it is possible to easily view Nikumaroro aerial imagery on line.
Certainly better resources exist but Google effortlessly offers enough quality and resolution to fire the imagination looking around to see where our lost crew might have landed and looked for food and water and shelter and might have stood waiting/hoping for a rescue ship on the horizon. Just go to
http://maps.google.com/ and start a map search for nikumar..... and then select the offering of "Nikumaroro Island, Kiribati". On the upper right of the map select "Satellite", then zoom in and look around.
(I see the wreck of the SS NC is disintegrated enough as to not be readily apparent [confirmed from recent expedition photos?], unless it can be pointed out under a wisp of cloud and Seven Site appears to be identifiable)
