Strange 'magic carpet' spotted over England
Some people thought they saw the flying carpet of Aladdin in the clouds. A spokesman for the weather service said that the cloud was an odd shaped aircraft trace. Although normally contrails appears in two lines , this track changed due to the atmospheric conditions in a rectangle, the spokesman said.
"In this case, a plane flown by an air pocket where the conditions were just right for the formation of contrails, the spokesman said." "The combination of the wind and the appropriate atmospheric conditions and the ice crystals in the contrail spread to the outside so that's how the rectangular cloud is originated. It is unusual that the edges can be seen that clear but it is a pretty common phenomenon. "
