Soon, massive flocks of birds attack. A national emergency is declared on BBC Radio, and people are told not to leave their homes. Then, due to the "unprecedented nature of the emergency," the BBC announces that it is going silent for the night and will resume broadcasting the next morning. For safety, Nat brings the family into the kitchen for the night. During their dinner they hear what sounds like aeroplanes overhead, followed by the sound of the planes crashing. The attacks from the birds die down, and Nat theorises that the birds will only attack at high tide.
