If there is hull insurance, the insurer will usually pay for security, until the aircraft can be recovered. The pilot/owner has some responsibility to arrange this if they are able, though it sounds like Maurice made fairly not be able.
Well, on my companies jets, South Sudan is a listed exclusion as it is classified as a war risk. I wonder if MK actually has insurance of sorts, and if he does, I wonder if they would cover damage to an unsecured aircraft? Let's hope it does not come to that.
