It's not about pilots supporting one another or otherwise, just about what's reasonable to claim compensation for (fundamentally, blaming someone else for something that happens to you and getting them to pay).
If it's a clear foreseeable hazard that the company or responsible authority didn't take steps to prevent and someone gets hurt, then OK.
If it's something that would be generally accepted by reasonable people to be within the normal capabilities of a person, then maybe not OK.
Obviously that's the $64,000 question.
My personal opinion is that the incident as described isn't something the company should have to pay for.
This isn't an attack on the bloke in question or a suggestion that companies should be immune from responsibility, but clearly many things can happen to you at work, but not all of them are the company's fault, or indeed anyone's, just bad luck.
