These pictures were taken when taking off from, and landing at, Bristol Airport, on a standard commercial flight. On occasions the flight routes start and end by turning one way or other over the estuary. It looks like a high tide on the departure pictures. The only picture from the 13th – landing – is the last one; of the Second Second Crossing – tide very much out!!
