This is obviously a very sad case. I personally have my doubts that you will be successful in your claim that Comed weren't the operators of the aircraft when the debts were incurred. You would have a case if the landing fees and fuel went through your account and you billed Comed but then it would just be you that were owed money then.
However if you have offered to pay off the debts that were incurred against your airframe i.e. the landing fees, fuel put into your aircraft and the VAT but the airport refused I'm not sure how the court will look at it.
Trade creditors / debtors are a normal part of business so I don't think you can claim the moral high ground by saying the airport shouldn't have let the debt mount up. SouthernAir owed a lot to Shoreham when they folded and they were a smaller concern.
I don't think jumpseater made the claims the way they are being interpreted by others.
Despite the fact that now most of you probably hate me I do hope that you get something out of this. You've already lost 18 months and I presume the first thing you will have to do if you win is spend even more money on an annual.
