There are the occasional planes that pretty much outrun the sm2 though.
See the map up there - those missiles were fired after each other, and then the target sped up and turned. The history trail seems to be gone though - and I don't have the original picture anymore, I think.
The overtake is down to only a small fraction of their speed, and the missiles are there on a heading around 90 degrees off the direction they were fired in.
