Only time and the investigation that will now follow will confirm or eliminate weather as a factor in this accident... Having said that, on a number of occasions over the years I've elected to delay a departure due to CB acitivity in the vicinity of an airport.. (or decided to hold well clear) ... in spite of the fact that ( in Europe ) I was losing my slot time... I'm always amazed by the fact that so few other crews take advantage of this simple alternative to flying into unknown weather conditions... why so keen to rush to the scene of an accident ? In Africa and one or two other places that suffer from very severe weather, and with no slot times to concern ourselves with.. why not sit comfortably on the ground for 10 / 15 minutes and see how things develop ?
