this may be a little OT but i thought some might find it interesting. it is the site of a group who visit pelau every year looking for american aircraft wrecks in the hope of finding mia's or at least giving some more info to the families of aircrew lost there. certainly a worthy project in my opinion.

also a Q that someone here might be able to answer for them re SBD's in pelau and/or the props on -4 -5 -6 SBD's. see the text and pics on this page
