Guys,
1. British Int t/a Veritair (a AOC holder) they have 5 in total S61s on their books.
2. They Charter these A/C to various Companies (ie Exec Galway in the case of G-VIPZ)
3. BIH also charter out to the UN (sister S61n G-BFRI i know has done service) and i would think IZ has too!! hence the Gun rack??
Air Harrods also charter out to operators and G-VIPZ was owned and operated by Harrods in a earlier life.
Hope this clears things up.
