This golf course has some unusual hazards - it's built between two runaways at one of the world's busiest airports. <br /><br />The 18 holes are laid out inside the Don Muang International Airport in Bangkok with flights every few minutes. Players tee off just 20 yards from roaring passenger jets - negotiating the unusual hazard of sliced shots flying onto the runway.<br /><br />Footage shot on May 19 shows just how near AirAsia, NokAir and other well-known carriers come to the fairways. <br /><br />A British holidaymaker said it was ''utterly surreal'' and expressed concerns about players being able to venture onto the runway. The keen golfer said: ''You're teeing off and there's literally an aeroplane going up 20 yards away. <br /><br />''One bad shot and the ball could slice right into its path. It's probably the only course in the world where you could be arrested for being a bad golfer.'' <br /><br />Don Muang Airport, which also has a Royal Thai Air Force base, has had commercial flights since 1924 and last year carried 40 million passengers on short-haul domestic flights and to destinations in Asia. <br /><br />However, aviation authorities slammed airport in June 2015 with the International Civil Aviation Organisation (ICAO) giving it a ''red flag'', which prompted sweeping safety changes. Despite players ID not being checked, every visitor now has to pass through an explosives detector and have their bags scanned. <br /><br />The course also has CCTV and players have to be accompanied at all times by caddies.
