Two went to the USA, both routed via Blackbushe 1977 ish, the first had been Franco’s personal aircraft with extra passenger windows installed and the gun positions deleted, it became part of the Commemorative Air force and they flew it until 2003 when it crashed and was destroyed unfortunately taking the lives of the two crew.
The second one followed also through Blackbushe and is now owned by the Cavanaugh Flight Museum, I did think it was potentially airworthy but the museum policy was not to fly it, see https://cavflight.org/index.php?option=com_content&view=article&id=60&Itemid=119 if you read the history of that one it states it was one of the aircraft used in the making of the BoB film in 1968 and then continued in Spanish service until 1975, I didnt realise they continued in use after the filming.
Sadly a third aircraft was the one that crashed on its delivery flight from Spain to the UK taking the lives of Neil Williams, his wife and his engineer.
