Well, I'll give you a clue: North West of Qatar, South East of UK. I am sure your "confidential reliable sources" will be able to help you. Oh and first initial A!
If you work that one out, I will be completely convinced that you were indeed top of the class!!!
Good luck in rejoining QR or indeed "any other Gulf Airline." If you get fed up over there, PM me, I might know someone that can assist you!
