Hong Kong TV viewers woke up yesterday to witness a historic moment when Egyptian archaeologist Dr Zahi Hawass (left) opened the door of a mysterious shaft in Giza's Great Pyramid to reveal a 4,000-year-old secret - another door.

When the world-renowned explorer used a robot to open the mysterious southern shaft inside the largest of the Giza pyramids, the world was watching him via live broadcast on the National Geographic channel. And what a let-down.

While we hoped for a wealth of treasure or at least a couple of mummies, Hawass had predicted there might be a papyrus or nothing at all. 'The presence of a second door only deepens the intrigue surrounding the Great Pyramid,' he chimed in. 'This is one of the first major discoveries in the Great Pyramid in some 130 years and now what we need is time for further analysis.'
