An eye-witness saw both explosions, but no plane. Shown by NBC at 16:58-16:59 September 11, 2001. This is a very important 9/11 eye-witness, because, besides being an actual witness to the two explosions in both Twin Towers, he is also an eye-witness to the fact that no aluminum planes have ever penetrated their thick double-walled perimeter columns each of the walls thicker than a tank's front armor. This is all related to the WTC nuclear demolition and to the fact that the alleged aluminum planes have nothing to do with the steel Towers' pulverization and with the strange nuclear name 'ground zero'
