Yes, the actuarial problem here is actually quite interesting, because one question it must address is the probability of failure. I wonder how much insight the insurers were given into safety margins on the spacecraft?
Haha, the 7% historic rate of satellites that failed to launch is not very far from my experience with the USPS' failed deliveries of postal packages to Australia.
I don't suppose you have other links to catastrophic risk insurance papers that are relatively interesting. I've always been interested in the industry from a far.
