   We are very often impressed and excited by amazing predictions made by scientists regarding our future: how we will travel, how we will spend our free time, how we will eat and so on. Apparently before long we will have gadgets that let you watch TV while navigating in your auto-pilot car which also makes coffee and sandwiches as you travel to the station. There you will catch an air-train, which flies along a rail without touching it and breaks the speed of sound. It would be interesting to be around in 150 years to see how many of these predictions are accurate, but for the moment we can content ourselves with some past predictions about how technology will improve or not.
   Some of the most important inventions affecting our lives concern travel, and one of these is the aeroplane. We will soon all travel by gigantic flying shopping centres according to some experts, but was everyone convinced by the aeroplane back in the beginning? Some people believed that the aeroplane would just never happen.
   For example, Mr. Simon Newcomb declared that flight by machines heavier than air is insignificant and utterly impossible. Eighteen months later the Wright Brothers flew. Another who believed it was impossible was Lord Kelvin. He should have known better, being a mathematician, physicist and president of the British Royal Society.
   The brilliant inventor Thomas Edison turned out to be a little short-sighted when looking at the sky: he declared in 1895 that the aeroplane’s possibilities were finished and that it was better to research something else.
