Chinese Rocket Seen Falling On a Village Spewing Highly Toxic Chemicals

Passant Rabie reports via Gizmodo: A video circulating online appears to show debris from a Chinese rocket falling above a populated area, with residents running for cover as a heavy cloud of dark yellow smoke trails across the sky in a frightening scene. The suspected debris may have come from China's Long March 2C rocket, which launched on Saturday, June 22, carrying a joint mission by China and France to study Gamma-ray bursts. The launch was declared a success, but its aftermath was captured by videos posted to Chinese social media sites. The videos show what appears to be the first stage rocket booster of the Long March 2C rocket tumbling uncontrollably over a village in southwest China, while local residents cover their ears and run for shelter from the falling debris. There are no reports of injuries or damage to property. That said, unverified video and images show a gigantic cloud erupting at the site of the crashed rocket, and the booster itself seemingly next to a roadway. The first stage of the rocket can be seen leaking fuel, the color of which is consistent with nitrogen tetroxide. The chemical compound is a strong oxidizing agent that is used for rocket propulsion but it can be fatally toxic, according to Jonathan McDowell, astrophysicist at the Harvard-Smithsonian Center. "It's known in the rocket industry as BFRC, a big fucking red cloud," McDowell told Gizmodo. "And when you see a BFRC, you run for your life." Nitrogen tetroxide was accepted as the rocket propellant oxidizer of choice in the early 1950s by the U.S.S.R. and the United States, however it became less commonly used over the years because it is extremely toxic, according to NASA (PDF). If it comes in contact with skin, eyes, or respiratory system, it can destroy human tissue, and if inhaled through the lungs, it can lead to a build up of fluids or, in extreme cases, death. "It's pretty scary, but this is just how the Chinese do business," McDowell told Gizmodo. "They have a different level of acceptable public risk." "I think over a 10 year period, we may see the older rockets phased out but they're not in any hurry to do so," added McDowell. "They're still launching one a week or something like that, and they are really quite dangerous."
