Shaggy Sheep Driver, attached is a graph of the SA-2 capability. You can see the Concorde, or its like, would not have stood a chance. You can see the 71 at its normal operating altitude had a very brief exposure. As I alluded to previously, one aircraft (an A-12 rather than a 71 I mentioned) did receive a small piece of shrapnel when a salvo of eight missiles were fired while over North Vietnam 30 Oct 67.
