The mistake
A photographer named John was flying first class from London to Nairobi in Kenya when one of the pilots came out of the cockpit to make some coffee in the microwave. He couldn’t get the machine to work, so he asked his fellow pilot to help him.
As the other pilot left the cockpit, he let the heavy metal door close behind him. The pilot started an urgent, whispered discussion with his colleague. The two pilots had locked themselves out of their cockpit and, as they told the photographer (who promised not to tell the other passengers), the door was fitted with a safety lock. This meant that not even the pilots could open it from outside the cockpit. John remembered that he had put his Swiss army knife in his hand luggage. However, he couldn’t remember where he had put his hand luggage and spent five minutes opening and closing overhead lockers until he found it. John and the pilots attacked the door with the knife, the lock started to come loose, and when they broke into the cockpit, the plane was cruising eastward over the Indian Ocean.

Tourists in Maya Bay
Maya Bay in Thailand made headlines in 1999 when Hollywood arrived there to film ‘The Beach’ starring Leonardo DiCaprio. Since then, tourists have flooded this beach with as many as 4,000 visitors arriving on boats every day.The mass tourism exhausted the once-pristine beach and ruined the natural life. That is why people closed the beach to tourists for four months. When it reopens by the end of September, they will impose a limit of 2,000 visitors per day.A marine scientist said that he and the other scientists made a mistake thinking that the money from the movie was very important, but now they see that the beach is a natural resource that they have to preserve. Zelda Tinska, an actress from the film, said that she honestly thinks that the West is a society which is obsessed with fame and celebrity. People do not visit the beach because they want to see the actual location but because there was a film shot there – and Thailand is an amazing country and there are many other beaches as beautiful as Maya Bay.
