News has just been received of an air crash in the north of England.The plane,which was on a charter (包租的) flight from London to Carlisl,was carrying a party of businessmen on their way to a trade fair.It seems likely that the plane ran into a heavy fog as it was getting close to Carlisle and was forced to circle for some twenty minutes.Everything seems to be going well.The pilot was in constant radio communication with Control,when the engines suddenly cut out and all contact was lost.The plane crashed on the site of the ancient Roman camp at Hadrian’s Hill,a place well known to archaeologists(考古学家) and tourists.
So far few details have been reported,but it is feared that at least twenty people lost their lives,among whom was the pilot,who was killed instantly.The local ambulance and firemen were on the scene within minutes of the crash,but additional help had to be rushed from other areas.
