Conversation so far:
What was Tambo's biggest honour?
In late 2005, ANC politicians announced plans to rename Johannesburg International Airport after him.
When was the airport officially renamed?
The proposal was accepted and the renaming ceremony occurred on 27 October 2006.

Question: Did he have any other notable honours?
Self-contained rewrite: Aside from having the Johannesburg International Airport renamed, did Tambo have any other notable honours?
