Answer:
We take air travel for granted, whether for business or pleasure, but what actually keeps an aeroplane in the air?
At any given moment, there will be approximately 10,000 planes carrying around 1.5 million people in the sky, according to aviation data organisation FlightAware’s recent research.
Further, the International Air Transport Association reports that in 2016 there were 3.8 billion air travellers – a figure it predicts will almost double to 7.2 billion by 2035.
Mind-boggling figures aside, how exactly does a plane stay in the air? It is just 115 years since the pioneering Wright brothers, Orville and Wilbur, flew 36m in 12 seconds on their history-defining piloted flight at Kitty Hawk in North Carolina, US. We have travelled a long way since then, but the basics remain the same.
