I was at Coningsby when the overhead heating was being installed in the hangars, the red piping that can be seen in your photo. This was not done for the comfort of the groundcrew but because it was beneficial to the aircraft and so overall cost of maintaining them dropped by more than the cost of the heating. When they were installing the heating in number 3 hangar we shared number 4 hanger (this one) with the BBMF as they had less aircraft in the eighties.
Our phantoms were in the far end and where this photo was taken from the Lancaster was up on jacks in flying position, that is with the wings not drooping due to gravity. It was having the wings re-skinned. As a result I was able to sit in all the BBMF aircraft they had at the time for a good look at them and sit in the various seats of the Lanc with the exception of the rear gunner. I wish we had had digital cameras then for a few good selfies.
We had a visit from my son with his wife and sons in August and went to a medieval event at Tattershall Castle followed by a visit to the BBMF then on to the Woodhall Spa Tea Room before heading home.
