Thanks to an uncooperative Blogspot, it took me all last night, early this morning and after work today to download all of those photos from my last post. Therefore this one will be low content, all of it scammed from a Japanese Tribute site called Indy Jones.jp. I'll roughly translate the Japanese for you, but some of them are beyond my capacity to do so. Any insight would be appreciated.

I think you can figure this one out for yourself. The call numbers on the side of Jock's (Frank Sorenson) plane who picks up Indy on the run from the Hovitos are OB-C30 an obvious nod to Obi Wan & C-3PO of Star Wars fame.
If you look closely, you can see C-3PO & R2-D2 in the heiroglyphics circled.
More trivia for later movies can be found at the same site here and there is a ton more trivia over at the IMDB page.
