Looks at some of the theories that have arisen and which one is now accepted to be correct, namely that of Polish astronomer Bodan Paczcynski who believes they come from collapsed super-massive stars on the edge of the observable universe.

Engines are the key to successful rockets. Ever since Robert Goddard flew the first liquid-fuelled rocket in 1926, scientists and engineers have been striving to make more powerful and more efficient rocket engines. The US approach was to deal with design issues on the drawing board, and test only when they thought the design was the best they could get. The Russians had a much more experimental, hands-on philosophy, building rockets and using full test flights to find out how to improve their designs. Surprisingly, it's the hands-on Russian technology that will power a new generation of US rockets into space.

Documentary about the Coelacanth, a prehistoric bony fish believed to have been long extinct until one was caught in 1938 off the southern coast of Africa. No trace was found again until May 2000 when a colony of the fish were discovered and filmed.
