My guess is that the plaintiffs are going after the insurance companies that cover the facility and/or the he event company that ran the wedding reception.

The fact that he wa fying the drone on private property, without permission from the owner, may also be a factor, by the time the dust settles.

My guess is that one or both of the aforementioned insurance companies will pay a settlement, and will subsequently seek reimbursement from the newlywed via. subrogation.
