I wonder how an Angolan company ever got offered such a charter in the first place. Of course, they are from a country where there is only one sure-fire way of doing business
If this was an episode of "Yes Minister" then sombody in Whitehall would be a member of the same gentleman's club as someone who played golf with another mason who worked for an Air Charter Broker who just happed to have a 747-400 kicking its heels for a few days. But of course "Yes Minister" was fictional.
