hang on, you've said to someone "I'm a pilot, I can fly this plane, come fly with me", they accept, and you think you can convince a court that you don't owe any duty of care?? Good luck!
Let me add that I really sympathise with Steve who has broken his back and his ^&*( "mate" is suing him over some clothes or some such stuff. And also I don't think Steve is at fault in any way. Steve, you don't deserve this and I hope youget better very soon and that the legal hassles go away.
