Whenever the crew’s pager sounds, they know they must prepare for all eventualities. At Beachy Head, the Eastbourne crew have to deal with a base jumper’s disastrous takeoff. Just along the Sussex coast in Newhaven, a man faces a race against time as he suffers a seizure on board a tall ship. At Loch Ness, a World War II sea plane runs into mechanical trouble. And in Rhyl, a dog chasing seagulls into the sea bites off more than she can chew.
