I just read Girl On the Ocean Floor. This was written by Lotte Hass, the wife of Hans Hass. It covers their first meeting to the end of their dive trip to the Red Sea and the marriage proposal by Hans. The book was the English version and was very easy to read. I liked Lotte's writing style even better than Hans, although part of that may be due to translators. I was raised on J. Cousteu and after reading about Hass I am surprised it took me so long to even hear about Hass. I have never seen any mention of him on US television. These folks were way out in front of the pack especially considering the time in history. Fun to read Hass's book about the red sea trip followed by his future wife's version. You can read between the lines and imagine Hass showing off spearing a shark (and being bitten).
I also bought the movie on German Amazon.com. I bought two sets:
Two disk "Klassik Edition":
1)"Pirsch unter Wasser" 1942
2) "Menschen unter Hain" 1947
3) Abenteuer im Roten Meer 1951
4) Unternehmen Xarifa 1954
5) Biographie Hans Hass 2006
There is also a 5 disk set "Hans Hass Dem Paradies auf der Spur" which has 12 films spanning 1974 to 2006.
German Amazon is cheap and looks just like Amazon.com in the USA. Google Amazon and German. I used Google Language bar to translate what legman I did not understand. They take the same credit card.
