The Unstable Explosives inside

A close look at the open garage door at a home in a wooded hilly neighborhood of Escondido, Calif., is where authorities recently found the largest supply of homemade explosives in a single location in United States history, Wednesday, Dec. 1, 2010. The home was rented and occupied by a George Djura Jakubec and is scheduled to be burned next week.

SAN DIEGO – Fire officials kept a close eye on weather patterns Thursday as they prepared to torch a house so laden with explosives that authorities have no other choice but to burn it to the ground.Wind currents and other weather patterns are hugely important in the highly controlled burn operation because authorities do not want a smoke plume to spread throughout the heavily populated suburban area. The burn was originally set to occur at 9:30 a.m. local time, but was delayed until 11 a.m. to make sure the weather is right.The house was rented by an out-of-work software consultant who allegedly assembled an astonishing quantity of bomb-making materials that included chemicals used by Middle Eastern suicide bombers. Investigators are still trying to understand his motivation for allegedly possessing so much bomb-making material.Bomb-squad experts determined that the residence was too dangerous to go inside, so they drew up plans to burn the home down. The home is so cluttered with unstable chemicals that even bomb-disposing robots can't be used to enter it. Authorities say the fire is expected to reach about 1,800 degrees Fahrenheit — so hot that it will likely neutralize the unstable explosives inside.
