It's alright Trim Stab, don't worry!
Our Typhoon's have PIRATE ( Passive Infrared Airborne Tracking Equipment ) as well as Radar. Not to mention monitoring by Ground Primary Radars, I don't think the target taking to cloud surfing will help him!
If's and what If's have to be dealt with as they occur. So of course; if there is non-compliance, then the decisions will be taken to minimise any collateral damage as possible and passed to the Interceptor Pilot for execution of those orders.
