Follow-up question for any lawyers out there: what does it do to the nature of the contract if the identity of the counterparty is undefined?
Stop wasting bandwidth. We will never see the inter party contracts, and don't need to. All that you need to know is that, by law, somebody is insured, and that the victims will receive some sort of 'financial' compensation. Pp is about the accident itself. For the benefit of aviation knowledge, not law.
