Let's assume the worst. You lob in to Cooly when it's a CTAF, in your 700Kg, uninsured RV-7 and somehow manage to cause a brand new 787 to be written off. Cue an airline (or more specifically, their insurers) on the warpath to get their shiny big Boeing replaced, without costing them anything.
They'll naturally try to sue the poor RVator, but he's only got (had) his RV and a house, maybe a newish car if they're lucky. Afterall - if they had more $$, he wouldn't be in an RV, he'd be flogging about in a Cirrus... So, the absolute
best they can get out of him is perhaps $1M AUD before he declares bankruptcy - and that's
if he doesn't try to mortgage his house & sell his car to fund the defence of the lawsuit and
then the insurer is going to get into a fight with the bank over who gets the house.
"Leave the country" stuff? Drip-feed a blood-sucking insurance company for the rest of your life? Nope. That
ain't gonna happen (Click
HERE if you don't believe me, look at the "Court-ordered restitution amounts"). They'll (probably) sue the owner, force them to cough up whatever they can, they'll in turn declare bankruptcy and the insurer will pay out on the Boeing and maybe claim on
their re-insurance policies...Realistically though, if all you have is a house and car, they
probably wouldn't even bother as
their lawyers would cost more than they'd get from you selling your house
anyway.
