This was how I spent my Saturday night and Sunday morning. The semi hauling butane, crossed a divided highway hit an embankment, went air born and landed in a ditch with three foot of water and one foot of mud. We had to extricate the driver, and and then deal wit hthe hazmat because the tank had to cracked valves. This included lifting and rotating the tanker to get all 9000 gal. of butane transfered to another rig. Over all a very long night at 12+ hours.
