AND TERROR ATTACK COINCIDING BY CHANCE (10yr mean) | One chance in | 3,715,592,613,265,750,000,000,000,000,000,000,000,000 |

| Estimate of Grains of
sand in the whole world (http://www.miamisci.org/tripod/whysand.html) | | 7,500,000,000,000,000,000 |

| | |

| In context: If I go to a beach, or a desert, or under the sea and pick a
single grain of sand. | | |

| What
chance is there of you going to the same part of the world by chance and
picking up the same grain? | |

| You are trillions of times more likely to do
this that the London drill coinciding with this attack at that
hour | |

| | |

| I wonder why the
media aren't reporting the drill?? | | |
