(NECN/NBC News: Michelle Kosinski, London) - A helicopter crashed Wednesday morning in central London during the morning rush hour near the River Thames.
Police say the helicopter crashed into a construction crane on a high-rise building and then fell to the busy street below. This happened during rush hour in a very busy part of central London.
A commercial helicopter trying to land because of the fog crashed into a construction crane on top of a tall residential tower here, cutting off a big chunk of that crane and sending the helicopter hurdling to the ground in a fire ball that claimed the lives of the pilot and a person on the ground.
"We were sitting having a coffee about half past seven and we just heard an explosion. It sounded like a fighter plane flying over, and we just heard a loud explosion and we thought there'd been a terrorist attack and we came straight out onto the main road, and there were these huge plumes of smoke," said Witness Matt Harverson.
A witness said the helicopter actually landed on top of a car which was also in flames.
"About a few seconds later there was another bang when the helicopter crashed into the road, just down there and a big fireball, black smoke and people were running around everywhere," Witness Ray Watts said.
One person was rescued from a burning car. At least nine other people were hurt, one critically.
Part of the investigation is whether the light on top of that crane was working.
