she doesn't know the reason for the go-around, which is why I've asked the question.
The reason was that it was the safest course of action. As it is with any go around. A go around is not a near death experience or a drama of similar magnitude. It is nothing more than a take off that just happens to take place while in the air. Should you be disappointed by this I am sure someone will be along soon to tell tales of how death was cheated at the very last moment.
