On the Edge Start-up Level Set 1 Book 4 Flying High

Mick King and Phil Johnson always seem to end up in the middle of trouble - they just can't help it. Phil is amazed when the local coastguard comes to school to tell the pupils about his job, and even more amazed when he learns he and Mick have won a trip around Brightsea in the coastguard helicopter. Amazement turns to astonishment when they have to help in a real-life rescue...but what's the turn at the end of the tale?
