the pilot and crew should be covered under whichever Workers Compensation scheme is in effect in Pennsylvania.
Once again there are limits and exemptions and many workers are excluded, or should I say employers do not have to pay. It comes back to the difference between forms of insurance in europe and that in the US. For all our winges in europe, if the insurer agrees the claim is covered it is paid in full. In the US you rarely get a significant proportion. A couple of years ago my US house was damaged by flooding in a hurricane. I had specific flood insurance and the damages were assessed and agreed before the insurer pointed out co pays and deductions and limitations which exceeded the total claim.
Lets not get into a debate about insurance. Suffice it to say this guy will be financially damaged as well as physically harmed and lets all contribute
