A1 accident 9/9

Did anyone else see that incident with two trucks on A1 South near Darlington on Monday afternoon? I was going North so didn’t get a good look but there was a white FH on hard shoulder with a tilt or tautliner that looked like it had fallen apart, all the offside and roof was on the carriageway. A bit further ahead of it on the shoulder was a Gerry Jones MAN with the cab nearly cut in half across the screen - A pillar on passenger side was severed but driver was out and looked OK and taking a picture. Just wondered what happened? Seems the knackered trailer took out the MAN but dunno how!
