If this follows the standard pattern then BA, Boeing and Rolls Royce will be named in any action, possibly the airport authority as well. Boeing were named in the Teneriffe, (Pan Am/KLM), accident despite it being obvious they had no part in causing it and immediately put $5million in the kitty as that was cheaper than defending themselves, (Boeing's Product Liability Insurance cover cost them $50 million p.a. in 1983 so you can guess what it costs today).
Remember that in the USA any award is based on the 'deepest pockets' theory so if found liable for say 20% of the blame you could finish up paying 80% of the award if you are deemed the richest defendant, well that is how it used to be, may have changed?
