True, Monty, there is some sillyness in this and other threads. But perhaps some of it can be helpful. What has been found in the so-called lantern or rat shields (or wheel covers) brings some interesting ideas, whether positive or negative to the Niku hypothesis.
1- native people to the islands are fishermen and fisherwomen, and are ingenious in improvising their methods.
2- what else could they have left that may or may not have anything to do with Amelia and her electra?
3- what have tighar expeditions found that may or may not be a part of the hypothesis?
4- the latest finds of Ric's discs in the landing channel may indicate there could be a lot more people interested in the island and landing there than we thought.
5- The discs of Ric and Spink are probably not related to aircraft, but are related to each other.
