There were a couple of days while we were in the Lake District when the weather was misty. In some places, it burned off as the day warmed up but in others it lingered. The Lakes can be a popular place for low level flying by military jets but, when the mist stays, there is not going to be sufficient visibility to get down low and fast. While I might have liked to have some planes come through, the contrast with the lower parts of the valleys in the clear with the mist on the hills around was very appealing.
