Thanks for this link.
Donīt know - only the investigators know - but if you take the
Airport and the last climb-out Position (FL 175) and the first FL 310 Position
that follows it, itīs a +/- straight line. Given how a large storm Shows up on
aircraft Radar, a larger avoiding-turn to the west would have been expected.
Donīt think that the storm was shown correctly on radar.
Maybe Equipment-Problem, maybe something else.
Any other ideas ?
