I have dashed over here, in response to a question asked by one of our grounded brethren on ARRSE, (an entertaining place BTW), about the effects of a Rapier shoot down on a large civilian passenger aircraft over London.
Surely a Raper wouldn't do more than knock a bit of a wing off or what have you, it would probably cause less harm to let such an attack run to its conclusion.
Kudos to the first person to suggest that Boeing/Airbus is better able to survive such a terrible thing, or not.
Sorry for the facetiousness in my topic, I mean no ill.
