A tragic video shows inside the cockpit of a helicopter that crashed while carrying a bride-to-be to her own wedding .
Rosemere do Nascimento Silva died in the accident alongside her brother, the pilot and a photographer who was six-months-pregnant .
The 32-year-old had planned to surprise her fiancé Udirley Damasceno, who was waiting at the altar when the chopper crash landed a mile from the reception venue in a rural area on the outskirts of Sao Paulo in Brazil.
Mr Damasceno and 300 wedding guests had no idea she had planned the spectacular entrance.
Police and air crash investigators are now trying to establish what caused the tragedy.
They are said to be looking into reports that it might have hit a tree during bad visibility with rain, fog and cloud.
“All brides have a dream and hers was to arrive by helicopter to their wedding without anyone knowing,” Carlos Eduardo Batista, one of the organisers told Brazilian media Globo.
The accident was only discovered when Mr Batista realised the chopper did not arrived at a nearby football field.
Mr Batista made a phone call which confirmed it had taken off as planned.
He and devastated guests were later told a plane had crashed nearby but it was first thought to be an unconnected incident.
The distraught bridegroom was told the news at the altar by the pastor and was said to have gone into total shock.
Although there were 300 guests at the wedding, only about six of them knew about the surprise.
The National Civil Aviation Agency has indicated the aircraft had permission to fly until February 1, 2017 with a capacity of three people without counting the pilot.
The helicopter – a Robinson 44 – crashed about a mile from the wedding venue in a forest area near a main road.
Eight fire engines rushed to the scene but nothing could be done to save the four occupants.
The pilot was named as Peterson Pinheiro, and the brother of the bride, Silvano Nascimento da Silva.
The pregnant photographer was Nayla Cristina Neves.
The journey would normally have taken just 15 minutes.
