Possibly... But many years ago a close friend of mine was landing in Luanda and she with half a dozen other passengers stood by the front door during landing. The cabin crew recommended that they should run for their connecting flight and this would give them a head start. But she need not have worried, the connecting flight was running on African time. Another colleague was flying for an A8 national airline and was rather concerned with his poor climb performance. A retrospective calculation indicated he was rather overweight. Part of the problem were the 118 people on a 101 seater aircraft. 15 year old children were checked in as infants. But to be honest, this thing is to be expected in any country where corruption is rife. God the poor EU when they let Albania in.
