It just proves how bad my memory is getting.
HX-OFC 257064 I flew on when it was HZ-NAD in March 1983 very shortly after which it was sold to Olayan and Registered HZ-OFC.
G-BKCD 256056 was first registered as such in July 1988.
I left McAlpine not long after this so the picture I guess was taken between these dates 1983 to 1986
I'm willing to be proved wrong!
For the sad people, and I'm one, David Reid is quite correct the two furthest away are real Viper powered aircraft. If you look closely you can see the tail cones are a natural metal finish plus the left unknown one has the blow off valve cover hanging down whilst G-BKCD you can just make out the hole for the BOV, the left one also only has 5 windows so probably a 3B/400 - I really need to get out more!
I'm home this weekend and I think I may have another picture from a different angle
What does worry me is how many of these aircraft which I worked on are now "parted out"
