Chinese Flight Cancelled After Passenger Throws Coins Into Jet’s ENGINE For ‘Good Fortune’ Before Takeoff: It’s said that you make your own luck, and a man boarding a flight in China has certainly proven that to be true. He was detained by police after throwing a handful of coins wrapped in red paper into one of the jet’s engines before takeoff. The reason he did this? For good luck, and it’s not the first time it’s happened. The flight was canceled and the 148 passengers had to find another way to travel. The coin-thrower had a nice, long chat with the police. No one is sure where the “good luck” came into the picture.
