You can sue for a breach of contract. You can say you're going to sue without physical contact. Threatening to sue in itself is not abusive or surly. And not a threat to the safety of the aircraft.
Someone using an idiom ('you'll have to frag me off') is not an invitation to violence. If Dr Tao had said 'over my dead body', that's not an invitation to carry that out.
