My worst landings were all at Nairobi on an Alitalia DC-10. There were about 8 of them and they all took place inside a space of about 20 seconds. At least that's how it seemed.
After that, I know why the Pope kisses the ground when he arrives after flying Alitalia.
I think my funniest take off was on a KLM flight, also to Nairobi, out of Jo'burg (in the good old days when we had to stop there). The FA announced on departure :
"Welcome on board this KLM flight to Johannesburg ...... sorry ...... welcome on board this KLM flight to Amsterdam ...... sorry ... welcome on board this KLM flight to Nairobi ...."
At which point a very loud, very Afrikaans, very beery voice shouted from somewhere in the back :
" Is you 
sure it's KLM, you doos ....."
