Dear Hans.
Please will you ensure urgent follow up on OliverTambo on the ATNS equipment not working.
Why is Air Traffic and Navigation Systems (ATNS) not doing the job they are paid to do.
They are causing risks to other peoples' lives, because they are to useless to do their jobs.
The National Body responsible for air safety. WHY DO THEY ALLOW AIRCRAFT TO TAKE-OFF AND LAND ON THIS AIRPORT IF CRUCIAL EQUIPMENT, SUCH AS MENTIONED ARE NOT SERVICABLE.

IT IS UTTERLY DISGUSTING!!!

Our institutions are rotten to the bone. On an airport such as OT, all equipment plus backup equipment should be verified for consistant operation.
Criminal charges should be layed against the people responsible.
We should not be wating for an accident to happen.
