Thank you for your replies.

Gipsy 1 (A) Can you confirm that the aircraft you are the passenger in is the same aircraft destroyed in 2002.
(B) Is it possible the remains returned to the UK sometime after the accident with the intentions to rebuild.
(C) I am convinced the c/n plate on the second airframe is from the earlier airframe.

I think we should probably regard the 18 years in store may not be that accurate. Also it may be that the 2nd airframe never flew ( Possible issues with the CAA )?
