THE FIRST JUMP
The first man to jump out of an airplane when travelling at a speed greater than sound was Arthur Ray Hawkins, one of the most outstanding United States Navy pilots. Jumps of this sort had long been regarded as impossible.
During an air show over Mississippi in 1954, Hawkins was flying an entirely new type of plane. At 40,000 feet, the nose of the plane dipped sharply. No matter how hard he tried, Hawkins could not pull it out of the dive and it gathered such speed that it was soon travelling faster than sound. Strapped in his seat, and hanging upside down, the pilot could not reach the button which would destroy the top of the plane.

THE PRINTING PROCESS
Today millions and millions of words are printed every day in books, newspapers, magazines and leaflets. But we sometimes forget that the process of printing started with an invention made by one man in the 15 th century. His name was Johann Gensfleishch zum Gutenberg; his invention was moveable type.
Before Gutenberg’s time, books were printed, but this was done from wooden blocks which were made by hand. Block printing was a very slow method of working. All other documents were made by scribes. The scribes copied everything out by hand. Moveable type put an end process the work of the scribes.
