Hi Adrian,this a bit late,and may be superfluous now that you have completed your model,but your original post asked for details of 8AEF a/c up to 1972.so,for what it's worth,I have just dug out my old ATC 3822,and I see that I flew from Shawbury on 23/9/72 in WP929 (10 minutes) and on 29/12/72 ln WK629 (27 minutes).
