Silverhawk. Althought not related to this topic directly I think you will find there were 2 companies back then. 1 called Janes Aviation and 1 called Janes Aviation (748). Janes operated the Heralds the other (obviously) the 748's. When they stopped operating the Heralds , not for financial reasons as far as I can remember Janes Aviation was wound up but Janes Aviation (748) continued. It was some time later subsequently re-named Emerald but again not for financial reasons.
On a seperate note hope it all works out for those involved.
