Completely agree old chap. In the case of QRA versus jet we know exactly what to do, when and how. (i.e. no need to exercise - we do it all the time) If anything the olympics makes it slightly easier as we may have a steer as to what a possible target would be.
In fact the 'business end' of an actual interception is probably the least valuable bit. The valuable bit is the exercising of the decision making process to launch and control fast air.
As regards co-operation with the police, using fast air for NTISR, SH for support or mobility, E-3 for strategic pie eating
etc I fully understand the need to exercise.
I have now convinced myself that this has nothing to do with a 2 v 1 over the borders.
