Wow, that was lucky John.
Glad everyone was ok. Must of been a shaky experience. I've never witnessed a blow out but have had one in my classic mini where a rear tyre basically unravelled itself from the tyre wall coming back from Cornwall. Had my girlfriend (now wife) as passenger and her Old English Sheepdog on the back seat. I was pretty shaken up but went into autopilot to change the tyre on the hard shoulder etc.
Truck tyres are at such high pressure I'm not surprised it sounded like an explosion sending bits of rubber and wire all over the road. My misses hit road debris that had been flicked up by another car and it did £2k worth of damage, car was only 6 days old
Was your car ok? Didn't get hit by anything?
On a lighter note, did you manage to winterise your 'van?
