I'm told that the old girl's last trip went largely unmarked beyond the aircrew. An instructional sortie, then shut down and chocks in. A significant proportion of the flight test community worldwide have flown that ac during training, and 44-odd years of service is not bad!
I guess times have changed, and management have little interest in machinery, nor feeling for the history at BDN. Methinks, though, that QQ missed a chance to highlight the fact that they are replacing 606 with something newer...
Au revoir, 606, I enjoyed flying you (even the day you slid off the runway at Duxford when your hydraulics failed...!)
