there is a problem with a "complicated" commercial air craft as far as taking off with a load while also turning while there's a cross-wind
the problem is: it's complicated
the above is likely "an estimated predicted flight plan". the plane crashed "somewhere after reaching 1000 ft" (this is well within the "take-off stall zone")
take-off stalls are never easy: they are the at least as dangerous as landing with a cross wind (which isn't safe, and may require computer aide in a large commercial craft)
