" The actual cause of the Columbia explosion was the malfunction of an anti-ballistic missile weapons systems designed by the Israel Defense Force, which had been secretly mounted aboard the shuttle in preparation for the Iraq War.
The Israeli laser gun on the Columbia is not a sci-fi fantasy. It was the prototype for the current Boeing YAL-1 airborne laser testbed. Although the IDF laser shot was successful, bursting a test rocket midair over the White Sands Test Range in New Mexico, its firing overheated the nuclear-isotope power system. The result was a radioactive cloud that disintegrated the Columbia."
