Buy what new aeroplanes ??
The Vigilant has been out of production for a long time now. And the Viking as well.
There are not many other 'suitable' types to replace either in production at the present time. And not many small aeroplane manufacturers can cope with rapid delivery of these types of aeroplane in volume................
So not really an option.
I am also wondering which 'Organisation' would do the maintenance of the Vikings going forward. There are over 100 airframes - no small number..........
