IT WAS a year of high-flying anniversaries, and more or less fond farewells. On 17 December 1903 the first spluttering aircraft took off at Kitty Hawk, North Carolina, and flew for nearly 40 metres. The Wright brothers鈥� airborne triumph was the beginning of flight as we know it.
A hundred years later, the world鈥檚 first supersonic airliner made its last commercial flight. Concorde took its passengers to the 鈥渆dge of space鈥�, as the PR blurb put it. But the supersonic dream came down to earth in October, somewhat to the relief of people living near airports in London, Paris and New York, who have had to endure the din of its regular flights for more than 30 years.
Fifty years ago scientists in the basement of King鈥檚 College London laid the foundation for all the recent genetic advances when they photographed DNA for the first time, with the help of a condom, some sealing wax and a camera full of hydrogen. Earlier this year we bade goodbye to one of the fruits of genetic technology, Dolly the sheep. The ovine superstar died prematurely aged 6 1/2.
It was also the year of the rugby world cup. Several of the teams, including the winners England, had shirts that were scientifically designed to hug bodies tightly, making it more difficult to tackle players by grabbing a handful of shirt. Unfortunately, the shirts also had the habit of bursting apart during the game. So while half the country could be heard expounding volubly in bars across the land about the finer points of the game, the other half were expressing a similar sporting interest in finer points of recently revealed pectorals.
And finally, it was time to say goodbye to the Galileo probe, which NASA deliberately crashed into Jupiter in September to avoid the risk of contaminating any life on the planet鈥檚 moons with aliens from Earth. So far this thoughtful gesture has gone without thanks.

How you scored
The scoring system works on the principle of snakes and ladders. You get 10 points for every right answer, and you lose 10 points for every wrong answer 鈥� so any score above zero is an excuse for a modest celebration.
