Don't think the insurers will pay up.
No, insurers certainly won't pay, it was deliberate!
FYI: the aircraft had a Special AWC under Experimental-Exhibition. There are a few US insurance underwriters that write policies for these type aircraft as this category is commonly used for unique aircraft, warbirds, etc. Now whether RB bought a policy I cannot confirm except that from strictly a liability standpoint vs hull-loss they would be stupid not too.
