G-ARTA the Prototype VC10 was converted from its original prototype form in 1968 to be an equivalent of the production 1103, however there were sufficient differences tha it received the unique type number 1109. This s where it gets interesting as the Aircraft was sold to Freddie Laker, but ever operated by a Laker owned company. It was then leased to various operators on short leases but ended up being a permanent part of the BUA fleet (G-ARTA, G-ASIW, G-ASIX and G-ATDJ), but as far as I tell remained in Laker Ownership even after the transfer to BCAL and the ‘unfortunate incident’ in early 1972 – The circumstances of which still irritate me after all hese years.

Thanks for making that clear – I was wondering if my memory had completely gone!
