Ian 16th, I was (groundcrew) on 83 Sqn (Mk 2 Vulcan) at Scampton in 61, 617 had the Mk 1A which were being replaced with the Mk 2 and 27 Sqn were forming with the Mk 2. Kicking the brain cells into gear the hangers were numbered 1 to 4 (L to R on google maps). No 1 hangar was 617 and their dispersal was bottom left hand corner of the airfield between the married quarters and 04 threshold (F dispersal I think). E dispersal (which was the same layout as F in 61 and is opposite No 1 hangar) was 83 Sqn dispersal. No 3 hangar was ASF and 27 Sqn had 4 Hangar. I dont think 27 had an allocated dispersal in 61 as they had only just started to receive aircraft. 617 and 83 certainly had their own dedicated groundcrew up until I was posted to Watton in 63. At Watton they had just introduced centralised servicing and it was universally hated by both tribes (air/groundcrew).
