Panic in New York!
One dead in New York steam explosion

An underground steam pipe explosion tore through a Manhattan street near Grand Central Terminal yesterday, swallowing a tow truck and killing one person.
Mayor Michael Bloomberg said the explosion was not terrorism, though the blast caused a brief panic about a possible attack.
"There is no reason to believe whatsoever that this is anything other than a failure of our infrastructure," he said of the 60-centimetre steam pipe installed in 1924.
One person was pronounced dead at Bellevue Hospital from an apparent heart attack, Bloomberg said. About 30 people were injured, at least four seriously. Authorities could not immediately account for how the most seriously wounded victims were injured.
The explosion caused widespread chaos as residents and commuters heard a huge blast - and feared for the worst. Thousands of commuters evacuated the train terminal, some at a run, after workers yelled for people to get out of the building.
A geyser of steam and mud shot from the centre of the blast, generating a tremendous roar. The initial burst of steam rose higher than the nearby 77-story Chrysler Building, one of Manhattan's tallest buildings.
A city bus was abandoned in the middle of Lexington Avenue, covered with grit. A woman who was bleeding profusely was being helped by police while a man lay on a stretcher in the street.
Soot fell from the sky, covering some pedestrians. Others looked wet. The sky was blackened. And people wandered aimlessly, not knowing where to go.
Debbie Tontodonato, 40, a manager for Clear Channel Outdoor, said she thought the rumble from the 6pm explosion was thunder.
"I looked out the window and I saw these huge chunks that I thought were hail," she said. "We panicked, I think everyone thought the worst. Thank God it wasn't. It was like a cattle drive going down the stairs, with everyone pushing. I almost fell down the stairs."
Heiko H Thieme, an investment banker, had mud splattered on his face, trousers and shoes. He said the explosion was like a volcano. "Everybody was a bit confused, everybody obviously thought of 9/11."
Streets were closed in several blocks in all directions. Subway service in the area was suspended.
The Buildings Department determined late yesterday that nearby buildings were structurally sound but suffered some water damage and broken windows. Several feet of street near the 7.5-metre crater was in danger of collapse.
There were also concerns about what was spewed into the air. Some of the pipes carrying steam through the city are wrapped in asbestos. "The big fear that we have is there may or may not have been asbestos release," Bloomberg said.
Officials won't know the test results until later, the mayor said, but if there was a release it may have washed away with the water that came with the steam.
The steam cleared around 8pm, exposing a crater several feet wide in the street. A red tow truck lay at the bottom of the hole.
Con Edison spokesman Chris Olert said workers were still trying to determine what caused the blast. Kevin Burke, the head of the utility, said the site had been inspected earlier yesterday after heavy rains flooded parts of the city, but crews found nothing at that time.
Millions of kilogrames of steam are pumped beneath New York City streets every hour, heating and cooling thousands of buildings, including the Empire State Building.
The steam pipes are sometimes prone to rupture, however. In 1989, a gigantic steam explosion ripped through a street, killing three people and sending mud and debris several stories into the air.
That explosion was caused by a condition known as "water hammer," the result of condensation of water inside a steam pipe. The sudden mix of hot steam and cool water can cause pressure to skyrocket, bursting the pipe.
