VCA's will happen. The other day I listened to a check and training captain in a metro bust straight into Sydney off the end of the YSBK zone due to being distracted. It can happen to anyone no matter how experienced.
I'm no proponent of VCAs but taking such severe action (license suspension) is retarded. All it would lead to is more 'transponder off dive bomb shenanigans' from people who now have something worthwhile to fear, not just a friendly letter from CASA.
