Maclolm, once again, It's a hypothesis. We are on a forum set up to talk about a hypothesis. You were dismissing all other parts of their landing on a reef hypothesis by saying the landing on the reef aspect of their hypothesis can't exist without Betty. When in fact their landing on a reef hypothesis existed before Betty was even included.
Yep a hypothesis and the fourth so far. We wait to see what this trip turns up.
Malcolm,
isn't that what Archaeology is about?
Dig a site, see some stuff, different colours in soil, items on or near such as burnt area and bone. Come up with hypothysis, such as food prep area. Another dig, another digger spots ceramics, hypothysis food prep area. More ceramics come up or match with urn similar to one found site 'X'. Site X suggested cremation/burial site, change hypothysis.
Seems to me digs from the 19th C were interpreted differently than digs now because of changes in understanding of what is happening at site.
Seems the same for TIGHAR but in less time scale.
Just an arm chair observation
