"If two events occur, the speed of the travelling Now is what keeps them apart. This is what stops everything happening at once, which would be most embarrassing, and lead to all sorts of conspiracy theories."

If you've ever been to the Kennedy Center you know the abundant helicopter traffic over the Potomac river. A Blackhawk helicopter collided with an American Airline jet from Witchita, exploded and both fell into the icy Potomac just minutes ago. The plane was on path to land on runway 33 at National Airport. There is no report of casualties or survivors. There is video of the collision.
The speed of the traveling now was unfortunate.
