Just looking at some old 202 pictures Gordon and by golly you are right. Could have sworn it was a 202 (DG) robbery but it obviously it was not. The plot thickens. (I do remember that we had a hell of a job getting hold of this electroluminescent panel for OAD, hence the memory).
I've just dug out some archive pics of the sim and the lighted cockpit mock from the 70s and they all have grey EL panels, so it did not come from there....and only the production fleet were this design.
....which aircraft was it filmed on?
G-BBDG
