Nonsense!!
There are plenty of well qualified IR instructors who are quite capable of taking up any slack. Ex CAA examiner starting in his place any day, as far as I am aware. The school also has a wealth of loyal ex staff and associated instructors / examiners / airline pilots who are more than ready to assist if and when necessary. Kevin was a competent instructor but in recent times in the opinion of many, had taken his eye off the ball to start his own sideline business. No-one is irreplaceable in this game.
LOST no longer.
