Skydiving has always been the top thing I want to experience! I've often imagined the thrill of jumping out of an aeroplane and free falling and floating gently to earth after pulling the parachute cord ( 降落伞绳 ). On my last birthday, I finally had the chance to try it - not in a traditional way!
I arrived at an indoor skydiving centre with great expectation and nervousness. The centre is equipped with a vertical wind tunnel (VWT) that allows people to experience free fall without a plane.
A VWT has fans at the top to pull air up through a flight chamber ( 飞行室 ) - the column that you step into to fly. The air is then pushed down the sides of the chamber and recirculated ( 再循环 ) back up into the chamber again. The fans can create wind at a speed of around 250 kilometres per hour in flight chambers, which reach about 5 metres in diameter and 17 metres in height. This process results in a safe cushion of air to float on.
After I arrived at the centre, I received some important instructions on how to position my body in the flight chamber. Next I was given a flight suit, a pair of trainers, a helmet, earplugs and goggles. The instructors helped me to put them on.
When it was finally my turn, I followed the instructions that I had learnt step by step. Immediately my body became horizontal as I lifted off the ground. After positioning me properly, the instructor released me, and I was “flying” on my own! I felt extremely excited when my instructor and I flew straight towards the top of the chamber!
I'll never forget this precious experience in my life. Maybe someday I'll really jump out of a plane, but for now, indoor skydiving is the perfect choice for me.
