It wasn't the real deal, but a simulated rescue mission on the Whanganui River on Saturday attracted plenty of spectators.
The exercise, involving an air drop of life rings from a helicopter and the Wanganui Coastguard rescue boat Energy Direct Rescue, was watched by at least 150 people standing on the riverside boardwalk.
It was one of the activities run by Wanganui Police staff as part of police open days held around the country this weekend. Staff decided on a Saturday because more people would be near the riverside.
Sergeant Colin Wright, who heads the local search and rescue operations, said it had been "a superb" open day.
"It went extremely well, and we attracted huge numbers."
