Helicopter Rescue
The children saw a helicopter.
"It's a rescue helicopter," said Chip. "You can go in and look," said a man.
The children went into the helicopter. They saw the cockpit.
"We pull people up with this winch," said the man. Rescue! Rescue! Rescue!
"It's a call out," said the man. "We must rescue a boat."
