After 37 minutes of flight, the pilots of an Air Canada plane were forced to declare a Pan-Pan alert, the second-highest level of emergency in a flight, because the smell of a shipment of the world's most fragrant fruit became unbearable. The 245 passengers and eight crew members of the ROU1566 flight had to return to Vancouver when the stench became unbearable.
The smell came from a shipment of durian, a tropical fruit that is known as the stinkiest fruit in the world. In fact, this is not the first time that this fruit creates a safety problem. Recently, an Indonesian plane had to perform an emergency landing because the smell of Durian caused a strong fight in the cabin. The fruit's smell, which resembles rotten onions or sewage, is known to trigger discomfort and nausea. After landing, the shipment was unloaded and the aircraft was able to resume service 20 hours after the original departure time.
