A man had to be rescued by a crane operator after falling down a giant 25ft concrete tank.
Nevada Fire Department were called to 270th Street in Iowa on Monday after an injured man fell down an industrial construction site.
Emergency services rushed to the scene as paramedics entered the concrete tank to try and stabilise the individual.
They set about trying to reassure the injured man as a crane was being ready to hoist him out.
However, as the tank was extremely hard to get into, the operation required a huge team effort to get the injured man out.
Crews had to balance the difficult rescue mission as they attempted to lift him out of the huge tank through a rescue basket, ropes, carabiners and a crane that was already on the construction site.
The "delicate rescue" saw the injured man lifted out of the tank and transferred to an ambulance on standby.
Fire services praised the joint teamwork that went into rescuing the individual as they admitted these type of incidents are often rare.
The collaboration between the fire services, ambulance and crane operator saw them all work "very calm under pressure" as they set about freeing the man from his nightmare.
Nevada Fire Department said in a statement: "Between the team involving the steady hands of the crane operator, Story County Sheriff dispatch, Story County Medical Center, Ames Fire Department and our own staff, this rescue was seamless."
The injured man was quickly sent to hospital and assessed at Story County Medical Centre where his condition was being monitored.
It is thought not to be life-threatening but further information about the injuries sustained are still to be confirmed.
The fall comes just hours after a window cleaner working inside Boston's s JFK Presidential Library died after reportedly falling at about 10.30am on Wednesday morning.
The individual, who has not been named yet, is said to have fallen five to seven stories.
Deputy Boston Police Superintendent James Miller said: "I would say about seven stories would be about three-quarters of the way up."

The director of the JFK Library confirmed the library would be shut tomorrow and reopen Friday as a matter of respect to the individual who tragically died.
