Blood In the Water

You flick the radio on and turn the knob to random places, saying "mayday, mayday, our ship is under attack by an unidentified creature!" You don't know if anyone got your message, so you look into the sky worriedly, hoping for a miracle.

As you're stare into the bright sky, you soon see a dark flying object. As it gets closer, you realise it has propellers on it.

It's a helicopter!

You feel a great relief, "somebody got the message!"

The rescue chopper winches you up into the helicopter, flying you away from the wreck.
