When I organised a TM two day visit in Somerset including Haynes and Yeovilton we managed to get a "Behind The Scenes Tour" through their (Haynes) servicing and rebuild workshops which was most interesting we thought. Some eye watering restorations going on to some beautiful cars, that trip took place during the workshop staffs lunch hour at around 1300 I recall.
This part has to be pre arranged but there was no additional cost at the time.
The carrier deck experience at Yeovilton has been totally revamped during the Covid closed time I was told by a friend so that should be a new experience again for the older hands.
