Lovely set. I had wondered where N4173T was, it used to be Cranfield based but judging by your photo it’s up for sale. Never did seem to move much at Cranfield really.
G-SKYE spent some time at Perranporth a few years ago when I was flying from there. Nice to see it’s still flying about.
A nice selection of airfields you went to. I’ve been meaning to go to Oxford airport since I saw how interesting it looked when I was at Thames Valley Police HQ last year.
