i was just watching Discovery Ch, and its all about "Mega Lightening".....they are showing photos that proove the space shuttle colombia, was not taken out by a faulty peice of the aircraft, like the news said, but a bolt of lightening. a 'mega bolt of lightening' in fact. they are also now the suspects for many unexplained airplane crashes. this mega lightening, known as sprites, its 6x stronger than a normal bolt. no plane is prepaired to be hit by one. its a shocking discovery. NASA originally confinscated the photos of the lightening hitting the shuttle, but they have now been leaked. check out discovery or discovery.com, they might have something for you.....
