When Court Line went bust the 1-11s were re-possessed by BAC pretty quickly.
My Father (a BAC Senior Inspector) flew to Luton from Hurn in the company HS125 with 4 BAC pilots and cleared the aircraft for the ferry flight to Hurn two at a time. I think the Liens on the aircraft were sorted by the commercial people.
Within about 2 or 3 days 10 of the aircraft were at Hurn with the word Court painted out so nobody would know where the aircraft were from!!!!!! (remember the colours)
The last of the 1-11s was stuck at Nicosia in Cyprus due to the war going on at the time. It was about 6 months later that my father was involved in recovering that aircraft.
This info is IIRC.
