The Treasure of Porto Santo
In 1724, a Dutch merchant ship sank off the Madeiras. A year later, an English diver, John Lethbridge , performed amazing feats of salvage. But how? Belgian diver Robert Stenuit reconstructed Lethbridge's ' diving engine ' to produce an intriguing historical detective story and a new development in underwater archaeology.
This film was a spectacular event for TV and produced with considerable courage. (DAILY EXPRESS) Producer RAY SUTCLIFFE
