Those were the good “old” days. IIRC the Jews were involved in the the shipping operation. Normally when speaking about the crew in this respect, I normally refer that to the deck and engine hands, the galley people but not the Captain!!!
It was Israel that helped Nkrumah to establish The Black Star Shipping Line, the Line was registered in Israel with THE ZIM LINE.
Nkrumah later turned his back on Israel in favour of the Russians.
