C16: Yes I understand. If you look at the photo of AXXO in the post you mention (#1279 on page 64) you will see how easy it was for 'Yoyo' to read her registration as 'XD'.
On the following page in post #1282 I do mention (by way of subtle correction) that the craft was 'AXXO' and which, up until that point, we had been searching for in order to help complete our collection of 'A' reg British JetRangers.
Not to be confused of course with Stuart Smith's G-AXGO (also seen on pages 64-55) which was later bought by Charles Hughesdon and which, to connect everything together, also ended-up in the drink!
