Sennadog - Although the instances you and others describe are unacceptable and just poor airmanship, the fact is that they are relatively rare and are not representitive of the generally high standard of flying in the UK.. .In 20 years of atco - ing and flying (ppl), working at busy airfields inside and outside controlled airspace, I can count the number of occasions on one hand when I've had to take avoiding action either as an atco or pilot.. .I wouldn't get too vexed about it, as you can see from the posts some people do and they'll worry their lives away. Filing paperwork only has a purpose if someone deliberately breaks the rules or there is a very valid safety issue which we can all learn from.
