A340 vs B747 ?????
Maybe we should ask some of the ex-Sabena pilots to 'inform' the masses of the different performances of these two aircraft using J'Berg as they changed in the late 90's from Bee's to Busses - funny I just did - the ex-chief pilot informed me that for the first time in their 80 year history they could NOT use the MTOW given in the flight manual for this airport - in fact usually 40t under. Their profitability went to hell and we all know the end result. I really do hope that SAA have done their sums correctly this time and not simply calculated on the purchase price!!!
Coincidence - you be the judge???
