Drilling for ?

The joys of holidaying at the brother's holiday house, means I can be forman/woman for the amazing drilling team. I think that Ziggy is and unfortunate name for a driller as we didn't want a Zag, just a bore hole for pure, fresh water.
The talk across the sitting room over a glass or 3 of red the previous evening, had turned to oil exploration and Blowouts. They get to the sandstone and then its oil, shortly after the gas. Well when overseeing ( rubbernecking), they had shown me the red sandstone and then suddenly ,Whoosh! The noise was incredible .......... as an RAF Tornado roared over the house. To say I nearly had to change my lingerie, was only just an exageration.
