"In the middle of a British swampland, not far from the Innercity, is a rectangular iron gate. Beyond its rusted bars is a collection of radio towers, abandoned buildings and power lines bordered by a dry-stone wall.

Every few seconds it’s joined by a second sound, like some ghostly ship sounding its foghorn."
"Lift-off on Wednesday is timed for 16:33 EDT (20:33 GMT / 21:33 BST)."
