Not covered by launch insurance (https://twitter.com/pbdes/status/771409425475174400), will be interesting to see if there is an insurance to cover that.

Of course it's not covered by launch insurance - it happened during the pre-launch stage. It was covered by marine cargo insurance.

Private launches are required to carry insurance in order to receive a license; I looked it up when the Orbital rocket had a similar RUD, and the government had mandated something like $140 million or so between government property contingency and general liability, if I recall.

Edit: Yeah, here's Orbital's (I can't find SpaceX's): https://www.faa.gov/about/office_org/headquarters_offices/as... -- last two pages. It looks like they revised this license recently for their return to flight, too?

It's possible to insure against business risk as well as asset risk, though it's usually not worth the premium. Though I've never been in the space business I would be surprised if it were not common for launches.
