Despite that they didn't do very well considering the Challenger had flown the entire width of the country out of radio comms on the wrong frequency! It was heading to Dublin and was intercepted near Shrewsbury.
TBF we don't know all that went on in the decision chain with that event but I suspect that comment might be a bit harsh - at least on the aircrew/aircraft side of things.
A quick look at the map will show that the geometry isn't favourable for a rapid interception. After which, if the Typhoons crews' brief was to take a look at the Challenger they've got to slow down to a safe and sensible closing speed in the later stages of the intercept, all of which eats up track miles, especially if the target is doing perhaps 0.8M or 0.9M.
You can only do so much with overtake, even if you got shed loads of it.
