I remember going down the docks to see the QE2. Grandad's comment was that it wasn't properly built as you could see all it's ribs 😄
I think he meant it wasn't riveted together but welded !
He was a machinist in the docks , Dad worked on diesel engine boats in the war including one of the D day command boats , he and fellow engine mechanics were allowed up to see the operation room with a scale 3D model of one section of the Normandy beaches .
