Wasn't it the other 747-8 that lived at BOH to replace the wonderful 747SP that lived there for years ? They flew for the ex-Qatari Emir and his daughter (?) if I'm correct. If so the 747-8 was gifted to the Turkish Govt after being unsold for some years due to the tiny market for VIP 747's
The 'HBJ' 747 has also been for sale (I believe) for the last several years and that too has been a busted flush so far. I think that it lives in Doha these days.
