LivingInthedream - I never said the SEY crew should maneuver and assume that the TCAS was not functioning correctly. I do not know WHAT they saw but they did feel that maneuvering was the safest course of action. They know the airspace has very little traffic. They likely, like myself, may have NO trust in ANY air traffic unit in Africa. They felt the situation warranted action and followed it.
No they are not heroes. It appears they did what they felt they had to do. So good work.
