When the US plane flies over the boat, another sail is glimpsed briefly over Diana's left shoulder.

When at the theatre for their final reunion, there is an air raid announcement and eventually aircraft are heard overhead and bombs start to drop.

There were V1 and V2 rockets, but doing away with the entire audience would not have fitted with the poignant ending.
