Emergency services took part in a large-scale training exercise based around a simulated plane crash at Norwich Airport.
More than 40 personnel were tasked with responding to a passenger plane that had been forced to land without an undercarriage on Monday morning.
Those taking part were told that the impact had resulted in a number of serious casualties inside the aircraft.
Firefighters from Sprowston and Carrow were joined by Urban Search and Rescue (USAR) teams from Norfolk and Essex, as well as the ambulance services' Hazardous Area Response Team (HART).
Starting at 9.30am, the airport's fire crews were first on the scene and had to spray the area with foam following reports that the plane had suffered a fuel leak.
Minutes later, the city's firefighters arrived to assess the scene, before USAR crews began looking at ways to cut into the plane's fuselage.
Station manager Jonathan Wilby said: 'We gained access to the fuselage quite quickly and our primary concern was to then get medical help to those inside.
'The HART team went in to assess and triage them, and we [the fire service] assisted in getting them out of the aircraft.'
In order to simulate the conditions of such an accident, real amputees were hired as actors for the scenario.
Along with children and adults, Mr Wilby said crews also had to deal with an overweight casualty.
Halfway through the exercise, it is understood that Norfolk's USAR crew almost had to deal with a real-life plane crash at Hunstanton, near King's Lynn.
It followed reports that an aircraft had crashed into part of a sea wall, but the crew was later stood down.
Mr Wilby said the training exercise, which was one of the largest in recent years at the airport, involved an aircraft that was due to be scrapped.
He said: 'It went well and we were really testing our partnership working. Urban Search and Rescue did the majority of the work and there were some minor learning points to consider in the future.
'We have to train for every eventuality and should something like that ever happen, we need to be well prepared.'
He said local crews train alongside airport firefighters around four times a year.
