Footage shows the moment locals approach the blazing wreck to help any survivors.
Just as the cameraperson shouts to anyone still inside the craft, it suddenly explodes, knocking the man to the ground.
The fatal plane crash took place in the rural area of Santa Rosa de Osos located just north of Medellín, Colombia, yesterday (21 Mar) morning.
The air ambulance took off from the Los Garzones-Monteria International Airport in Montería at around 6.10am to travel to Medellín to pick up a patient.
The plane is understood to have encountered a technical problem in midair and lost communication while flying over Santa Rosa de Osos about an hour after departure.
It is believed the aircraft then struck a tree on its descent before crash landing in the field.
The victims were all residents of Barranquilla.
According to the authorities, the plane was a Beechcraft C90 with the registration HK4684.
It was owned by the company Inversiones Aeronáuticas BPA SAS and was subleased to the medical firm Sky Ambulance SAS.
Sarabia Carrisoza had been working for Sky Ambulance for three years and Gómez Pinzón had been with them for four months.
Dr Vanegas had been in the job for a month while Marañón Medina had been a nurse for the company for four years.
An investigation into the crash is ongoing.
