Pull Harder
The relationship between Shell Brunei not flying at night and having never had a ditching is one that I am struggling to answer on my postcard.
Not flying at night doesn't mean they couldn't have one during the day and if they did fly at night it doesn't follow that they would have one day or night.
In fact, I am not sure about the point you are trying to make but please don't worry since I don't wish to enter into prolonged correspondence with you about it.
