Hi，O.P.
Mao's last flight was in 1967, as I stated before. He was dorced to take a IL-18. He never took any flight in his life after that. The trident used his name to attract tourists. No plane in Chian was privat except the crashed 256 trident. By that time, Mao had refused to take plane, so Lin was the only one got this honour.
I would like to go to Mongolia, but Mongolians are also unbelievalble. Once they said they've got the "black box" of 256,and heard some fight on board! That is white lie! Anyway, thank you for the suggestions.
regards
