I thank all who have pointed out that I am not a pilot (I did first) and should therefore have no hand in further matters. What a compliment!! Especially from Bruce Wayne whose best shot at this is to post some very, very old photographs of long ago.without contributing a single word to the subject in hand, the Oxford Union would be proud of you Bruce, take a bow.
LHC - You did not explain your wild conjecture over the future defecit which would require more up to date figures. Please elucidate.
TRSS - If I can be bothered I will give you a detailed answer to your points, they are ALL wrong. However in relation to you a,b,c points, you are only b. Does that disqualify you?
