Only got good things to say about them. It is a very busy airspace and they handle everything form student pilots to scheduled DC-9's of Sunair. Sure, the odd incident does occur, more due to inexperienced pilot's i.e. students in such a busy airspace than anything else. Bearing in mind they have no radar and sometimes johannesburg radar literally dumps an aircraft on their doorstep.
Friendly and helpfull bunch with a great sense of humour. Not strange to have 8 plus aircraft on TCAS within 10 miles. all terminal traffic inbound/inbound FALA.
They also make mistakes every now and then, but don't we all ?
Keep up the good work.
