First excuse my English. Im Slovak.
Here is map with all locations of airplane parts. Finding wreck of airplane has been not so hard. I found it like first. Second I found only piece of wing on opsit side of lake. After two rounds around lake and trying finding last of piece I told myself, its must be out of lake but not so fareaway... I went on top of hill into rock round for finding last. Nothing.
When I was going back to lake I found last. Engine with part of wing. Great. I was lucky man
Sorry, texts on map is in my language because I translate game into my language for myself...
