A couple of weeks ago we went with school to Dutch Mil ATC, they proudly explaining that they respond extremely quickly to comm failures and intruders. Yet now it seems they did nothing?
The military don't move until
civilian ATC established there might be something wrong, and tell them. I gather the fighters were dispatched promptly once the airforce command was informed.
Keep in mind that this was only a comms failure. The aircraft apparently didn't deviate from its established course and presumably the transponder continued operating normally as well. Had the aircraft been doing weird things, in all likelihood ATC would have alerted the military much sooner.
