Just to bring this story to an end, after 3 months and being kept dangling, I get a phone call yesterday to say 'sorry, the company has stopped trading'.
Bah humbug.
Probably a blessing in disguise, but still very annoying.
Back to the drawing board then. (Anyone want to offer a biz jet job to a relatively low houred - 1300tt - , relatively nice guy like me ?
)
