Ahhh, Al F, but I think even you will admit that on reflection, you're missing the point completely. If said VVIP's could arrive and depart from some anonymous military base, no one among the great unwashed would be reminded of how important they are.
I'm sure i'm not the only one who trolls this site who remembers the Sultan of Johore, who used to keep jet airliners in the hold while he did circuits at VJR in the ***ing microlight.
Someone I'm sure will correct me if I've got the details wrong, but I understand that one Oz FO with MAS one day made so bold as to suggest over the radio that this might just be a tad over the top. He was made to fly down to Johore on his day off and hand deliver his written apology to a senior lackey of the Sultan's.
