Imagine yourself traveling by plane for 11 continuous hours, with all the fatigue and exhaustion that accompanies you, and then you return from where you came.
This is what happened with the passengers of a Dutch airline "KLM", last week, according to the newspaper "The Independent" British, Monday.
The paper said the plane took off from Amsterdam to Mexico City, but after flying for five and a half hours, a decision was made to return to the Dutch capital.
It took the same time to get back to the airport, making it one of the world's longest flights ending where it started.
The pilot made the decision after learning that the Popocatepetl volcano, near the Mexican capital, was in a state of eruption, which means it is difficult to fly in the skies there.
The company said in a statement that the eruption created "unfavorable flight conditions", such as ash rising to the sky.
Another reason for the Dutch plane to return was carrying a load of horses.
KLM's flight was over Canada when it was decided to return to Schiphol airport in the Netherlands.
Airlines are usually looking for an alternative airport in emergency conditions, but this has been stalled because of the large load of horses.
The incident took place last Thursday, and eventually the flight landed safely at Schiphol airport. The airline said it would reserve an alternative flight for passengers.
