Contrail
I've seen this aircraft four times here in North Wales. It comes from the direction of Ireland and over to Chester. This aircraft flew right over head last Sunday about 12 noon. The thing is there were lots of other jets flying over as well, jumbos, etc. They all made a sound and left the usual vapour trails behind them...
