Tourists are flocking to a beach directly under the flight path of jumbo jets to feel the impressive force of their jet stream as they pass just 20 metres over head. The Boeing 747s blow sand into the faces of avid plane spotters who gather at cafes near Princess Juliana International Airport on the Caribbean island of Saint Martin. They sit waiting for the planes to approach before dashing to the road and beach to feel the 300-tonne aircrafts blast past at about 150 miles per hour. Many tourists duck as they realise just how close the deafening planes are passing above them. Planes - like the KLM jet pictured - are forced to pass just 20 metres above the beach as they come into land on the shortest runway in the world that 747s regularly use. [CFP]
