C/n was used by the aviation registration body in the U.K. pre WWII. The term certainly was not introduced by Air-Britain! If you use the CAA site and look at the following link to the first card recording the registration for example of G-ACTF you will find the term “Constructor’s Number” already in use.

This Spitfire was subsequently on static external display at Old Warden in unrestored condition until a decision was made to return it to flight. This how I first remember it. (Link to photo credit “rac819”) https://www.flickr.com/photos/rac819/40450382974/in/photostream/

Having done a little research, I now suggest that the Messenger in 633 Squadron may have been Messenger 4A G-AKZX. This was owned by Neville Browning from 1948 until withdrawal from use in 1967. In fact it ended its flying life in 1965. This aircraft had a dark scheme and its registration was carried in small letters on the outer fins. In the film an indecipherable red registration can just be seen in that position as they enter the aircraft; but it is Browning’s ownership that may be the main pointer to which aircraft was used.

I thought the B-25 which moved to Belgium was the ex Coventry and Santoft machine “Big Bad Bonnie” used in the Hannover Street movie and not N9089Z or has that recently departed?

My post wasn’t related to Daz. I was just musing over the sad loss that occurred back in 2001. It is wonderful to see this Spitfire recreated.

He brought the Weeks Solution over to the World Aerobatic Championships at South Cerney in 1986.

As “backdrop” means behind or beyond, my point was that the areas behind the runway and the display line are not compromised.

I have been attending OW since the 1960s. For many years visiting aircraft were parked on the far side of the runway. No matter whether those aircraft were interesting types or not, they were always in view behind the displays and sometimes spoilt the background to photographs of the display aircraft landing or taking off.

I think the present arrangements are fine. In certain conditions the WWI and Edwardian aircraft are (during the flying display itself) parked at the far right, to reduce their distance to the runway leading up to their slot; that would not be feasible if visiting aircraft were parked in that area.
