Hi there Would it be possible to tie in aircraft modifications with aircraft history. Whilst looking at A340 9H-BIG. I noticed that it started life as F-GTUB A340-313. It then became 4R-ADF being modified to A340-312, which was duly recorded. It then became M-VVIP (was still a -312) But is recorded as a -313.9H-BIG is recorded as a -313 (should be a -312).When an aircraft is modified is it possible to change details, so modified aircraft goes hand in hand with history of aircraft. Thanks Ron
