Hello P1fel.
Yes, and I had the privilege of being told it by Hazel himself. A nice little touch. He had a pen that had been presented to him by the HP management. Said pen was in the holder alongside the seat. After the remains of the Herald were extinguished, one of the firemen returned the pen: undamaged. The Herald was, I believe, being accompanied to Farnborough by a Hastings. If any pictures were taken, they don't seem to be in the public domain. I guess since it was supposed to be a trip to drum up sales, such pictures would have been quickly destroyed.
Leeds/Bradford with a wind of about 220/25, gusting 35. I'm sure you remember it well! Not only did it sort the men from the boys; it also sorted the men from their hair.
